I got an infection on my leg from an bite and went to the er to get it checked out and they opened my abscess and prescribed me Bactrim. I made sure i was talking it to get rid of the infection and didn't want to go through that pain again. Then 4 days later I started running a high fever and nothing I did could get it to stop. It would go away for an hour or so then come back. I assumed I was getting the flu cause I had a fever, bad body aches, and I had nausea and stomach ache. But I could not figure our why I had chest and back pain. Well then the next morning I woke up with a major rash all over my body. From my head to my toes, I went straight to the emergency room and they told me to stop taking the bactrim and gave me Prednisone and Benadryl. This has been the worst experience of my life. I don't think they should use this drug at all. It has the corst side effects and they take a long time to recover from.
