Perez Hilton is back in the hospital after doctors discovered a "massive" blood clot in his body. "Last night, I started having real soreness and pain in one of my legs. This morning, it got way worse. I couldn't even walk. I had to use a walker," Hilton, 48, said in a video posted via Instagram on Thursday, April 2. "I've already seen some of the nurses who took care of me for 21 days when I was here fighting and beating sepsis thanks to these amazing doctors, nurses and God. Now I'm back, and I have to have emergency surgery.
