Nurse!

Bam Margera landed in the hospital shortly after starting his third stint in rehab ... but he's assured fans he'll be just fine.

The "Jackass" star was hospitalized Wednesday to treat what he says is edema ... swelling in the body caused by blood vessels leaking fluid into the tissue. Bam wrote in a since-deleted Instagram post that he was in the hospital for only a few hours to treat "either reaction to new medicine or detoxing from i guess a bit of alchohol [sic]." Bam's already back in rehab.

TMZ broke the story ... sources close to Bam told us he put himself back on the road to recovery last week when he voluntarily entered a new rehab facility. He had been at an L.A. bar the night before checking into rehab. He had recently bailed on a treatment facility ... the second time he's done so this month.

A romantic rafting trip turned bloody for NBA star Kevin Love and his model girlfriend, Kate Bock -- when the couple fell overboard and she bumped her head ... requiring staples to close to wound!

The two were rafting in Wyoming when things went south ... they were riding in the front of the inflatable raft (without helmets) when they were ejected from the boat.

They were smiling in the water -- but when Kate was pulled back into the boat, it was clear she suffered a head wound ... so they wrapped her in gauze and raced her to a nearby hospital.

Kate -- who's modeled for everyone from Sports Illustrated to Victoria's Secret -- required a few staples to close the wound ... but she's brushing the whole thing off as no big deal.

Despite a bloody hat, Bock and Love were in good enough spirits after the accident to trek out to dinner at a local sushi joint ... and even smiled for a selfie!

BTW -- the rafting company claims it was the first head injury they've witnessed in 34 years. Of course.

Love and Bock have been together for years. They also have the most adorable dog. Shout-out to Vestry.

As for Bock's rafting career ... she says she WILL hit the waters again someday.

We believe in you, Kate!!

A lightning bolt struck a PGA Tour Championship golf course this weekend -- and it ended up hurting a number of people ... including one kid.

The scary moment happened Saturday afternoon at the East Lake golf Club in Atlanta, GA at 4:45 PM ET, when lightning struck a tree in the middle of the third round of the FedEx Cup Championship -- which was on a brief break amid stormy skies.

The lightning reportedly sent a bunch of debris flying, and that struck at least six people ... one of whom was reportedly a child. Nobody was hit by the thunder bolt itself, and thankfully ... no one is said to have suffered life-threatening injuries. Terrifying, nonetheless.

Paramedics arrived shortly thereafter to treat the victims, and the scene couldn't have been more chaotic with folks lying out, waiting for help ... and being carried away on stretchers. Eyewitnesses on the ground say the moment sounded like a bomb going off on the course ... and you can see why.

The moment the lightning hit the tree was captured on camera from afar, and even in the still images of the strike ... you can see sparks, if not outright fire, emitting from the tree. There are reports of the tree catching fire, but it must've been put out quickly.

When ya mess with bull, ya get the horns ... right in the balls.

That's the lesson decorated matador Paco Urena learned when he stepped into the Vista Alegre bullfighting arena this week at the Semana Grande Fair in Bilbao, Spain ... where he ended up with a crotch full of horn.

OLE!!!!!!

Unclear how badly Urena was injured in the incident -- but it seems like his man-junk survived because there are photos showing Paco proudly showing off the bull's ears as trophies.

As you probably know ... the bulls are mercilessly tortured and killed during the fights. As you can see, Urena was wielding a sword during the fight, with the intention of stabbing the bull through the heart so it can die fast. But, that rarely happens because the bull doesn't want to die!

So, what ends up happening is a bloody, painful, torturous exhibition in front of thousands of screaming blood-thirsty fans ... but hey, TRADITION RIGHT?!?

Tee Grizzley is mourning the loss of his manager after his car was riddled with bullets Tuesday night as he rode around Detroit.

Law enforcement sources tell TMZ ... the deadly shooting went down Tuesday night, when a gunman opened fire on Tee Grizzley's Cadillac Escalade. We're told the rapper's manager, Jobina Brown, was sitting in the back seat.

Our sources say the SUV had stopped and Tee Grizzley was getting out of the front passenger seat as the shooter approached on foot and pulled the trigger ... hitting Jobina in her left side. The driver of the SUV told cops he heard Jobina scream right before 3 to 4 shots were fired.

We're told it's unclear if Tee Grizzley was targeted in the attack -- but neither he nor the driver were hit.

Carlos Carrasco is a BEAAAAAASSSSTTTT ... 'cause just a few months after being diagnosed with cancer -- the Indians star took the mound again, AND THREW 97 MPH!!!!

Cookie hit the injured list back on June 5 after docs told him he had leukemia. He was feeling sluggish ... and nobody with the team knew if he'd be back again this season.

But, Carlos fought like hell the past few weeks to get back on the diamond ... and the dude looked like he hadn't missed a day of throwing when he made his first Minor League rehab start for Double-A Akron on Monday night.

According to MLB.com's Mandy Bell, Carrasco hit 97 MPH with his first pitch of the night ... and followed that up with a few more heaters at 96.

The Indians stud finished with one strikeout, one walk and no hits or runs given up in his one inning of work ... and he left to a huge cheer from the crowd.

"It feels great because those people were behind me the whole way," Carrasco said. "From Day One until now."

Unclear when Carrasco will officially make his return to the Indians' big-league roster ... but manager Terry Francona said he anticipates having Carlos back in the bullpen sooner rather than later.

As for his timeline on a return, Carrasco said, "I'm ready to go."

Ronda Rousey is so tough, she BROKE HER FINGER on the set of the "9-1-1" TV show -- BUT NEVER BROKE CHARACTER!!!

Ronda -- who plays an L.A. Fire Dept. badass on the show -- was shooting a scene in Mexico last week in which she was supposed to slam a door during a dramatic action moment.

But, as one source put it ... "She was a little over-exuberant and slammed the door on her finger."

We're told Ronda didn't wince, didn't complain, didn't mess up the scene ... instead, she continued to stay in character and finished the scene.

Only after the director yelled "cut," we're told, Ronda FINALLY acknowledged the injury -- saying, "Ow. You're not gonna like this!"

Ronda went to a doctor who diagnosed her with a broken finger -- which is NOTHING for the former UFC superstar.

She got a splint for her hand and went right back to work the next day, our sources tell us.

Hollywood ... it ain't for the weak.

NASCAR dropped an awesome "thanks for saving our legend" gift over the weekend ... donating tickets to the first responders at Dale Earnhardt Jr.'s plane crash -- and seems they loved the gesture!

44-year-old Junior was involved in a fiery plane wreck last week, where he, his wife, his daughter and two pilots miraculously survived when their aircraft went down in Elizabethton, Tennessee.

Everyone involved in the accident thanked the town's first responders for making sure they all got out OKAY ... and as a present, NASCAR gave them tix to Saturday night's Bass Pro Shops NRA Night Race at Bristol Motor Speedway.

"We had a great time with our first responder family at the BMS night race!" The Carter County Sheriff's Office said.

"A big thank you to NASCAR for giving us and all the agencies that responded to Dale Jr.'s plane crash free tickets!"

Dale also chimed in with a thank-you message of his own -- breaking his silence on the crash -- writing Monday, "We are truly blessed that all on board escaped with no serious injuries, including our daughter, our two pilots and our dog Gus."

"I am thankful for the quick response of my pilots, local law enforcement, emergency personnel and hospital staff."

Abel and Ola Osundairo are back in Nigeria, but this trip has no Jussie Smollett connection ... the brothers are there offering free medical services in their homeland.

Abel and Ola returned to Lagos this week ... far from the ongoing Jussie drama in Chicago.

The brothers organized a free medial outreach program, offering various free services ... like checking blood glucose levels and blood pressure, and calculating people's body mass index. Doctors were also on hand, prescribing medicines and treatments.

The brothers set up shop outside a local business and hundreds of people showed up to take advantage.

Remember ... the last time the Osundairo brothers were in Africa, they had just staged a fake attack against Jussie on a Chicago street -- at least that's their story, and cops and prosecutors believed them. Jussie says the "attack" was real.

This trek was all about community service and healthy living ... and no one cut them a check for $3,500.

Dale Earnhardt Jr. is SERIOUSLY lucky to be alive today ... National Transportation Safety Board officials just announced his plane bounced TWICE on the runway before it eventually crash landed.

Junior, his wife, his 1-year-old daughter and the two pilots on the plane all miraculously survived after their aircraft crashed in Elizabethton, Tennessee on Thursday.

NTSB officials updated media members on some of the details of the accident ... revealing the whole thing was caught on surveillance video -- and it sounded scary as hell.

The lead NTSB investigator, Ralph Hicks, said he could see the plane hit the runway two times before the right landing gear on the aircraft collapsed on the runway.

Hicks said the plane -- a Cessna Citation Latitude 680 -- skidded down the runway, through a chainlink fence and into a ditch before it came to a stop near the local highway.

Hicks said all five passengers -- and Dale's dog -- were able to get off the plane in a matter of minutes ... before massive flames engulfed the aircraft.

Hicks said the flight was only a 20-minute one from a nearby city in North Carolina.

NTSB officials have yet to determine a cause for the crash ... saying it could take about week before their investigation concludes.

Dale Jr. -- who works as a race announcer for NBC -- is taking the weekend off after the crash. He's expected to try to return to his broadcasting job next week in Darlington.

For their part, the Earnhardts released a statement on Friday through Dale's sister, Kelley, saying, "Dale, Amy, Isla and our two pilots are doing well."

Antonio Brown just broke his silence on his frostbitten feet ... telling media members out at Raiders camp that the blisters are making it hard for him to play football.

"It's been a process with the feet," Brown said ... "Anytime you got a lot of blisters, it's hard to change direction, cut and run and be able to do what I do naturally."

Brown has been battling frostbite ever since he suffered a mishap in a cryotherapy chamber ... but he's been silent on the matter until he returned to Raiders camp in Napa, Calif. on Tuesday.

Brown wouldn't say exactly how the freak injury happened -- only revealing the whole thing has sucked -- but he did say he believes he's getting closer to returning to the field.

Remember, when Olympic sprinter Justin Gatlin joined the guys on "TMZ Sports" (weeknights on FS1) ... he said when he suffered a similar injury, it took him MONTHS to get back to full health.

But, AB seems somewhat confident he'll be ready soon ... saying he's been working with a foot specialist to inch closer to 100 percent.

By the way, Brown also addressed his whole helmet drama ... saying he's working with the NFL to try to get him the Schutt he prefers.

Vicente Luque OBLITERATED Mike Perry's nose and he didn't quit ... and that's why he says Platinum's the toughest dude he ever faced.

Luque landed a big knee directly to Perry's nose during their fight Saturday night -- literally crushing it -- turning the fight into a blood bath.

Perry kept fighting.

TMZ Sports talked to Luque ... who was blown away by Perry's toughness.

"Obviously, I wanted to get the finish, but it didn't happen that night. Mike is so tough. As tough as they come. For sure the toughest guy I've faced 'til now."

That's a big deal -- Luque once beat Thiago Santos -- the guy who just pushed Jon Jones to the brink of defeat while fighting on a bunch of torn ligaments in his knees.

And yeah, Vicente says Perry is tougher than Santos.

The fight was a war ... and the guys pummeled each other ... so friends is probably the last thing you'd expect they become, right?

Wrong ... 'cause Luque tells us they've actually talked about training with each other.

"[Perry] talked about training, and that's something that in my mind is super positive. I love training with different guys. He's a guy who has a lot to teach me, for sure."

Candytopia's marshmallow pit is shallower than the social media posts -- for which it's popular -- according to a visitor who says he learned the hard way ... DON'T JUMP IN!!!

The interactive candy museum is being sued by a guy who claims he jumped into the marshmallow pit exhibit -- which he says looks deceivingly like a deep swimming pool -- and SHATTERED HIS FOOT.

According to a new lawsuit, obtained by TMZ ... the man claims he went to Candytopia in San Francisco earlier this year with his fiance, and museum employees actively encouraged him to hop into the marshmallow pit.

Problem is ... the guy says the pit has the look and feel of a swimming pool, complete with a familiar style in-ground swimming pool ladder, but no one told him there wasn't a deep end. The only warning he says he got was to hold on to his cell phone -- which he claims made it sound like the pit was at least waist-deep.

In the docs, the dude says as a result of his injuries he had to wear a walking boot ... and he claims his broken foot ruined his wedding and his doctor told him he'll likely suffer foot pain for the rest of his life!!!

Now, he's going after Candytopia for damages and looking for a sweet payday. If he's awarded a pool of money ... we're guessing he won't dive in.

Wayne Newton's monkey ain't your average Curious George ... cause the teenage girl who says the animal bit her says the injury required medical attention.

TMZ's obtained a pic of the injury allegedly caused by Wayne's Capuchin monkey, Boo. The girl's mother is suing Newton claiming Boo bit her daughter's right wrist 2 years ago while visiting Newton's former estate, Casa de Shenandoah ... a tourist attraction and museum in Las Vegas.

Their attorney, Marc Naron of D.R. Patti & Associates, says the bite broke the girl's skin ... causing it to swell -- and she had to go to a hospital where she got a tetanus shot. The pic, btw, was taken the day after the alleged incident.

We're told the alleged victim, who was 15 at the time, underwent follow-up treatments and was left with a gnarly scar that may be permanent. She claims she underwent counseling because of her fear of animals.

In the lawsuit, the family says Boo was not caged nor on a leash when they visited back in October 2017. Wayne and his wife, Kathleen McCrone Newton, tell us they haven't seen the lawsuit. They add ... their company stopped operating Casa de Shenandoah in July 2017, "due to Wayne's almost dying from a spider bite" -- so they have "no idea what happened in October 2017."

Mystikal took a terrible fall during a concert Thursday night in Tampa ... it was so bad his concert got cut short by more than half and he couldn't walk off the stage without a major assist.

The rapper ran onstage at around 1 AM and within 30 seconds just at it ... he tumbled offstage to the floor below. Security helped him back up, but he was clearly injured and in pain.

He spent the next 45 minutes grimacing in pain as he sat on the edge of the stage ... unable to stand. At times he scooted a few feet, but that was it.

A concertgoer tells us, it was obvious to all something was seriously wrong, as Mystikal repeatedly said, "Man, I need an ambulance."

He finally pulled the plug as members of his crew helped him offstage without putting weight on the injured leg.

It's unclear if he went to the hospital.

Willie Nelson worried his fans when he abruptly canceled his tour due to a "breathing problem," but the singer's only taking a temporary break and will return soon ... TMZ has learned.

Willie's rep tells us his tour schedule is typically 2 weeks on, 2 weeks off, but his recent medical issue -- which they believe is linked to his history of emphysema -- is requiring a little extra R&R this time.

We're told he's only officially canceled the next 6 stops on his tour ... but plans to return to the stage September 6 in Gilford, NH and continue on with the 20+ shows scheduled after that.

As for the breathing problem ... Nelson's rep says it was not a medical emergency and he wasn't rushed to the hospital or anything like that. He just needed rest and is back in Texas to see a doctor.

We're told he's currently taking it easy and already feeling better.

Willie's 86, though, and this isn't the first time he's had to cancel some shows due to his health. He missed the Outlaw Music Festival last summer and had to cancel some dates earlier in 2018.
