Lou Ferrigno has been hospitalized after a pneumonia shot gone wrong.

Ferrigno famously played the Hulk in the 1970’s Incredible Hulk television series. Now 67, Ferrigno revealed a regularly scheduled pneumonia vaccination left him in much worse shape.

The actor shared on Instagam that he was administered a pneumonia shot that ended up leaving fluid in his bicep. The actor reassured fans that he’s alright, while also revealing a picture of himself on a hospital gurney, hooked up to an IV drip to help him get over the mistake.

“I’ll be ok,” the actor included in the post, but he also warned that “it’s important that you keep an eye on who’s giving the shot and make sure they not only swab the spot correctly but that you watch the needle come out of the package.”

Ferrigno is a frequent user of the social media platform, usually sharing pictures of himself alongside other celebrities and working out. This post was a little scarier than most, so it’s good to hear that the Hulk will be back on his feet soon enough.
