i had an insect bit on the side of my knee, a very minor one, i even remember when the insect bit me. 2 days later it was swollen and very red. I was convienced to go to the doctor, thank fully I did. He said that i have staph. He didnt culture it but somehow thats what he told me. I started the anti-biotics and ointment friday, and its working, but the pain is horrible only when i stand with out any weight on it, just standing. but at other times i can walk as uaual, but shortly, like 2 mins. the pain is back. What is going on?
