So I've been sick over a month now with still no answer from the doctor. I originally was put on an antibiotic to get rid of a sinus infection. From there I started to get this terrible pain in my side that grew worse. The doctors said it could be c diff or a parasite because I was also having a change in bowel movement. THey treated me with Flagyl and I felt stlightly better. Here I am weeks later with the pain still in my side, off and on nauseau and a discomfort/pain in my penis when the pain flares up. I am wondering if it was the antibiotics that were making me sick to my stomach before and if this pain in my side and groin with nauseau is actually something else. Nobody seems to help. I don't know what to do.
