bacterial infection
"My doctor put me on Sulfamethoxazole in hopes of clearing up a mild but reoccurring skin infection under my arms. I was instructed to take 2 pills per day for 2 weeks.  My first, second and third day I felt okay, but the fourth - ninth day (today) I have felt very tired, shaky and dizzy.  When I turn my head a certain way, or lay down, I feel as if I spun in a circle ten times, then stopped. I called today, and spoke with a nurse who assured me that I would have had the side effects the first or second day. Well, I know my body and I don't feel right. So today will be my last day on this."
