Nurse!

Richard Simmons went to the hospital Monday for "severe indigestion" ... according to his rep.

Richard had been battling "discomfort while eating" for several days, and finally decided to get treatment at a hospital on Monday.

His rep, Michael Catalano, told ABC News ... Richard was already doing much better and expects to make a full recovery.

Our sources say the "gastrointestinal issue" wasn't serious enough for an ambulance, and Richard's people drove him to the hospital.

This is the second time in the last year Richard's had to leave his home -- where he's been sheltered for years -- for hospital care. Last summer, he was at Cedars-Sinai for 3 days after his housekeeper said he'd become incoherent.

His people said that was a case of dehydration ... which seemed weird for several days of treatment.

We now know why the woman injured at a Tyga concert persisted in collecting money even though Tyga's company has made it clear they don't want to pay her ... she got really messed up.

Shyanne Riekena already won a judgment against Tyga's company for injuries sustained when a light stand came crashing down on her, leaving a 4-inch gash on the top of her head.

As we reported ... Tyga's music company got slapped with a $236,000 judgment but failed to pay. Now, with interest, the judgment has swelled to $250k.

Shyanne says she's been suffering for 5 years and is indignant Tyga's business won't own up.

Richard Simmons is "perfect," and "happy," but he's still dealing with a knee problem that has kept him in virtual hiding for the last 3 years ... that's the takeaway we got from one of his closest friends.

A woman named Denise -- who says she's known Richard for 35 years -- was at Richard's gate delivering flowers where she said the former fitness guru is doing great.

But then she says Richard's been dealing with a medical issue for years -- his knee. TMZ broke the story back in November, 2014 -- 8 months after Simmons just disappeared -- that he had 2 bad knees and an operation on the first was so painful he was delaying the second.

It seems that based on what Denise is saying ... Richard was bedridden for a time because he never got the second knee operation. Unclear if he's gotten it done yet.

The woman 50 Cent punched square in the chest is now going full bore against the rapper ... lawyering up for a lawsuit.

Donnetta Derr has a law firm behind her that will sue 50 early next week. She'll also sue The Lox, with whom Fiddy performed, and the venue, Baltimore Soundstage.

TMZ broke the story ... 50 was performing last week when the woman grabbed his arm and pulled him off stage. 50 retaliated with a vicious punch.

Donnetta later went onstage and twerked ... leading people to believe the beef was squashed ... nope.

Attorney Warren Brown tells us Donnetta went to the hospital the next day and hired him Monday.

Brown calls 50's conduct "cowardly."

Another attack on a United Airlines flight, and this time it was a scorpion that got its revenge on a passenger.

Richard Bell was on a flight from Houston to Calgary Sunday when a scorpion reportedly fell from an overhead bin and stung him. The flight crew contacted a doctor on the ground for medical advice.

United says his injuries were non-life threatening and medical personnel took care of Bell when he landed in Calgary.

United flight attendants are shocked David Dao was brutalized and bloodied because police could have prevented any injury if they had a clue about the plane they boarded.

We spoke to several United employees who say the officers should have known the armrests on those seats are movable. Remember, Dao's head slammed into the armrest, causing at least some of his injuries.

The flight attendants point out the cops could have effortlessly lifted the armrest before forcibly removing Dao ... who appeared to get hung up on the middle seat armrests before hitting the one on the aisle.

The employees we spoke to made it clear they believe Dao should've been removed, but they're fuming at how it was handled.

United's CEO says they're reviewing its procedures in these situations, but flight attendants think it's the police who need more training.

Paging Dr. 2 Chainz ... Dr. 2 Chainz to the OR, stat!

Words we imagine no patient would want to hear, but that's what went down in Miami when 2 Chainz stepped into surgery for an up close view of a Brazilian butt lift.

The rapper streamed parts of the procedure Thursday on social media as the actual physician, Dr. Michael Salzhauer ... aka Dr. Miami ... went to work on a woman who dropped $10k for the procedure.

We're told the patient fully signed off on 2 Chainz sitting in, plus Dr. Miami was also streaming. Chainz, had full scrubs WITH all of his chains hanging outside though.

Verne Troyer has been in a San Fernando Valley hospital bed for nearly two weeks for alcohol addiction ... TMZ has learned.

Verne tells TMZ, he's been receiving treatment for alcohol abuse for a week, however we're told he entered a hospital days before that.

Verne says by the end of this week he'll be checking into a rehab center for help.

Verne has struggled with alcohol abuse issues for years ... he almost died in 2002 from alcohol poisoning and has gone to rehab multiple times.

He gives a shout-out to fans, saying, "With your support, I got this."

It's official ... Dustin Johnson is OUT of the Masters.

The PGA superstar says he injured his back Wednesday falling down stairs at the house he's staying at near Augusta ... but tried to soldier through the pain Thursday morning.

Johnson is the #1 ranked player in the world and was the heavy favorite to win the tournament.

Johnson took some warm-up shots at the driving range -- but cut it short. He was seen holding his back in pain afterwards.

He even went to the 1st hole and tried to go -- but decided to throw in the towel.

Dustin Johnson is taking some cuts -- hoping he can fight through the pain and play at The Masters Thursday.

The 32-year-old says he injured his back Wednesday falling down stairs at the home he's staying at in Augusta and was unsure if he was going to have to withdraw from the tournament.

Johnson hit the range this morning and took some swings before cutting the session short and holding his back.

But a short time later, he grabbed his clubs and went back to the practice range. He clearly looks uncomfortable, but will try to tough it out.

Championships = bonfires.

Bonfires = burn injuries.

Officials in Chapel Hill tell TMZ Sports 4 people suffered burns from the victory fires on Franklin Street following the Monday night championship game.

The stats aren't bad considering there were roughly 55,000 people partying their faces off.

We're told no arrests were made and only 7 people were injured (including the 4 burn victims).

Officials say the fires were extinguished and cleaned up without further incident and the streets were reopened to vehicle traffic around 2 AM.

A rep for Chapel Hill tells us, "The Town would like to thank all its many Town employees and area partners for a collaborative effort to watch out for the safety of the people of Chapel Hill."

"The Dudesons" star Jukka Hilden took a big shot with a new stunt Friday ... and it's painfully entertaining to watch.

Half of the 4-man stunt group from Finland joined us on "TMZ Live" Friday to show off a new feat of insanity -- using a pressurized t-shirt cannon to fire thumb tacks, Lego parts and chunks of cactus into Jukka's chest (and throat).

We'd like to say this beats getting chomped on by an alligator ... but the jury's still out.

Pretty obvious now why Eric Clapton had to cancel his L.A. concerts -- the rock legend was rolling in a wheelchair as he jetted out of town.

We got Clapton heading into LAX Wednesday ... a few days after he had to pull the plug on a couple of weekend shows due to severe bronchitis. The illness has clearly knocked him for a loop.

One of Eric's daughters held his hand as he was wheeled to his gate. He's rescheduled the L.A. shows, and it's unclear when he'll be able to get back on the road.

Speedy recovery, EC.

Drake had no choice but to cancel his Amsterdam concert because he had a prior engagement ... with a bathroom, due to extreme food poisoning.

Sources close to Drizzy tell us he ate some bad sushi on Monday, and it messed up his stomach. We're told it was so bad he had to get medical treatment immediately. It wasn't enough though ... he was still too sick to go onstage, which seriously pissed off the entire arena full of fans who'd already been waiting in their seats for 75 minutes when they got the bad news.

It was the third time in 3 months Drake had to postpone an Amsterdam gig ... which explains why fans threw crap onstage. He's promised to make up the show Wednesday.

We suggest a simple bowl of rice beforehand.

Burt Bacharach's being sued by a dog sitter who claims the mutt chewed off 2 of his fingers, requiring surgery using a skin graft from his groin.

Joel Gayner says he volunteered to take care of Alfie -- a Portuguese Water Dog like the ones the Obamas have. The 73-year-old sitter says one early morning he woke up to Alfie gasping for air, urinating all over the place with its eyes rolling back.

Joel says he dislodged a plastic bone on which Alfie was choking by pressing on his chest, massaging his esophagus and up the windpipe before broken pieces of a plastic bone came out of Alfie's mouth -- along with thick mucus and saliva.

He says this saved Alfie's life but minutes later, when he went to pet him, Joel says the dog snapped and mauled his left hand. The bite was so bad, Joel says his middle finger needed to be surgically reattached. What's more ... he says his index finger was also bitten off and he needed a skin graft from his groin area to reattach the missing chunks.

Joel says his fingers now have dead zones -- no feeling in multiple areas. He's suing for medical expenses and unspecified damages.

We've reached out to Burt, so far no word back.

A fan died in the stands of a live WWE event Saturday night.

It happened at a house show in Portland, Maine where an elderly man reportedly collapsed out of his seat in the corner stands as the 2nd match of the event began.

EMTs moved the man to the nearest flat area and proceeded to conduct CPR for about 20 minutes -- before taking him out on a stretcher to a local hospital. During that time, EMT's performed CPR and 2 matches went down.
