I was bitten by an insect last week in Trinidad (horrible place). It has become infected badly. I went to an urgent care Dr. and he gave me Bactrim. I've been taking this for 4 days, but it's only getting worse. It's in my arm pit so it's very uncomfortable. There were about 10 bite marks, and 3-4 have swelled up the size of a golf ball.
Question is, what should my next step be? How long before I should expect the Bactrim to start working or will it? I didn't get it cultured so no positive id! Very painful, along with fever and chills.
