I started taking the Antibiotic Septra a few months after birth. I continued to take Septra until age tweleve when I decided I no longer enjoyed taking it daily. I currently suffer from Rhuemtoid Arthritis, Fibromyalgia, migraines, and am being tested for CREST Syndrome. I swear long term antibotic use has had much to do with these issues proving it seems to be whats difficult.
