Hi, can I answer your health question? Please type your question here...Hello. I had swelling in 1 leg (right) and developed cellulitis. My Dr gave me Keflex and Mupiricin Ointment. Two days after that my left leg,ankle,and foot swelled tremendously and my right foot swelled up and it wasn't like that before. And it's not cellulitis. I'm kind of scared because I used IV drugs about 5 days before this happened, with my left leg. It was present in my right leg for about 2 weeks. I have psoriatic arthritis and psoriasis which compromise my immune system and also Hepatitis C. Please help. When I went to the Dr the second time she ordered bloodwork, which I immediately got done and an echocardiogram for next week and to stay off my feet. She asked me if I used any street drugs and I lied and said no. Please help. I'm a nervous wreck.
