Last September I was prescribed Clindamycin for a toothache. About four days into it, I developed what I thought was an unrelated flu, followed by diarrhea. The diarrhea got progressively worse. On the last day it was accompanied by a slight fever. The dentist who prescribed the Clindamycin suspected C. Diff and gave me a prescription for Flagyl. Four days into Flagyl I developed a high fever and went to the doctor. The doctor took blood and stool. No C. Diff in the stool (I later found out it is hard to detect if you're on Antibiotics ) and the blood showed abnormally high white blood cell counts, indicating my body was fighting off some kind of major infection. Re-tested blood a week later, back to normal, but the diarrhea continued. Went to a Chinese doctor who prescribed herbs that did nothing. Went to a GI who suspected post-infectious IBS, ran more stool tests, no C.Diff, no parasites. Went to Southeast Asia for a conference, got really sick. Came back, more tests, nothing revealed. Diarrhea alternated with soft or ribbon like stools, some abdominal pain. Back to Southeast Asia, got sick again. Came back, more tests, more Chinese medicine. The GI gave me Hyoscyamine because he thought it was IBS but it gave me the worst cramps I've ever had and I stopped it. I finally changed GI doctors. New GI put me back on Flagyl for two weeks. Made my diarrhea worse. When I went off it for the first three days things seemed as if they were resolving, then went downhill from there. New GI ran a colonoscopy, capsule endoscopy, CT scan: all came back negative. Found a new GI who suspected continued C.Diff infection saying tests for C.Diff were inconclusive and tricky. Wanted to put me on Vancomycin. I didn't take it because I was afraid what it might do. He also sent me to a tropical disease lab who did a purged stool test and found Blasto. He also isn't sure it's causing my symptoms but he wanted to put me back on Flagyl. I said no way. He now wants to put me on Bactrim, but I'm suspiscious of it. I've been doing a parasite purge from "Healing with Whole Foods": ten days on, five days off of Wormwood , Black-Walnut or oregano oil or Wormwood , Black-Walnut , and Colloidal Silver . Nothing for breakfast but raw brown rice. No other grains, no breads, basic candida diet. That seems to have gotten things under control and they're better than they've been all year, but I want my body back: My symptoms now are inconsistent bowel movements, sometimes firm, sometimes loose, sometimes ribbon like stools, occasional bouts of diarrhea but nothing like it once was, pain after eating dinner (I sometimes feel as if I've overeaten). Not sure if my body is healing itself or crying for help from the big guns. The odd thing is that this happened to me once before, over ten years ago, the last time I took Antibiotics . The doctor diagnosed it as a kind of yeast infection and gave me Diflucan which didn't do much but eventually the problems resolved themselves after about four months. This time I haven't been so fortunate. I'm thinking of taking the drug cocktail recommended by badbugs.org but it sounds really lethal and wonder whether it's going to make me sicker. Or should I try the Bactrim the doctor is offering? No faith in doctors anymore.
