I've been taking flagyl for an abscess and fistula for awhile now and it is nassssssstyyyyyyyyyyyy! It makes food taste bad and water taste like the worst possible thing to ever put in your mouth!
For my first abscess, I took cipro and flagyl and the abscess went away.
For my second abscess, I took cipro and flagyl and the abscess ruptured, causing a fistula extending superiorly to the rectum in September.
My GI is making me take flagyl again, but I don't have alot of hope for it to remove the abscess and remove the fistula.
I don't know why the flagyl worked one time, but not the next. In both cases, I was asymptomatic as far as I was concerned and both under stress. I guess my body just responded better to the flagyl the first time. It may or may not do the trick for you, but since you're getting another abscess (in a different spot?), it doesn't seem likely.
Good luck and let me know if the flagyl works for you!
Diagnosed with typical Crohn's at 16.
Got lucky with Asacol for a year, then even luckier with ten years of relative remission.
Now abscesses and fistulas are having an "atypical" Crohn's party around my junk.
My HMO refused the Remicade and now I could be going on Lialda or sulfa? blah
