helicobacter pylori infection
"Started taking amoxycillon, omeprazole, and clarithromycin to treat H. Pylori. Worst side effects I have ever experienced. By day 4, I had severe diarrhea (looked like coffee grounds), nausea, dizziness, couldn't sleep, would have waves of burning through my chest and into my head. I went to the ER because my breathing was labored and I had such severe diarrhea. I also developed something oral thrush so my tongue felt so raw. My doctor finally told me to stop taking it.  The side effects were extremely miserable and torturous."
