bacterial infection
"I was prescribed Bactrim and Keflex to treat an traumatic force injury to my shin which a month later turned into a bacterial type infection. I was on these 2 anitbiotics for 3 doses (100 mg Bactrim) and I got small spots of hive-like bumps under both forearms, on my hand, and on the backside of the injured shin. They took me off those antibiotics and without taking any other medicines yet that day, approximately 8 hrs later I looked like I had the chicken pox. It's Day 3 after stopping Bactrim and I'm just starting to get some relief from the intense itching ( I did have a steroid IV today to try to help this)."
