I am a 26 yo male in otherwise good health. Took 1200mg/day Clindamycin orally for 2 weeks to treat a serious jaw infection after oral surgery. Clindamycin treatment ended August 12. For the rest of August I was under an extreme amount of stress and anxiety, was drinking more heavily than usual, and noticed loose bowel movements 1-2x per day, but I chalked it up to the anxiety and stress.
Last day of August I had a noticeable amount of diarrhea followed by some mucous and blood. I remembered that Clindamycin can cause bacterial dysbiosis so I started eating yogurt.
In early September took 7 days of Flagyl for the loose BMs. No real improvement. Saw gastrointerologist in early September. She suspected bacteria because of the history of Clindamycin AND a clear Sigmoidoscopy (to 88cm) that I had in December of '04 for an unrelated issue that turned out not to be a problem. GI gave me 3 weeks of Flora-Q probiotic in September. Also had an abdominal X-ray in September when I had a bad lower chest pain. It showed nothing interesting other than gas in my upper left colon.
Before August, I was completely normal. Normal for me was eat anything I want and have 4-5 hard BM's a week. Since end of August, I have been dealing with one soft BM per day, never feels complete, vague discomfort in my upper left abdomen a few hours after I eat, or before and after I have a BM, general bloating, a come-and-go feeling of not being well in my gut, and a lot of abdominal activity and discomfort just before and 1-2 hours after my daily soft BM.
I see the GI again in December. For a week now I have been trying Grapefruit Seed Extract twice daily, fiber, green tea, and probiotic pills. All I can say is that overall, I feel SLIGHTLY better than I did in September, but not much! I don't know what this could be, or what I can do!
