Tom Segura Says He 'Couldn't Wipe' After Horrific Basketball Injury

Tom Segura is opening up on the awful injury he suffered while playing basketball in 2020 ... saying the damage was so bad, he couldn't even wipe his own ass.

The 42-year-old comedian ruined his arm and leg while attempting a dunk during a hoops sesh with fellow funny guy Bert Kreischer ... and if you haven't seen the video yet -- it's worse than you could ever imagine.

But, if you REALLY wanna check it out, click here -- but you've been warned. IT. IS. BAD!!!

In fact, Segura even needed a nerve transfer to help fix his arm ... after he already had pins and screws put in.

Segura joined Big Cat and PFT Commenter on Barstool Sports' "Pardon My Take" to break down the days following the incident ... saying he couldn't even feel his leg injury because his brain was focused on his arm.

"I was just like, 'Oh my God, my arm is so f***ed,'" Segura said. "And it was shattered. So I was just like, 'Goddammit.' And they were just giving me f***ing Dilaudid into my neck. I was like, 'Give me more!!'"

But, the severe pain medication -- along with a nerve blocker in his leg -- came with some crappy consequences ... and Segura gave every detail about the "assistance" he needed from nurses in order to go #2 at the hospital.

Yeah ... we're not going to put it into writing, but you can use your imagination or check out the clip.

However, Segura said he couldn't even wipe his tush on his own when he WAS able to take care of business ... and shared the hilarious reaction one nurse had when he found out what he was going to have to do to help out.
