All your symptoms could be a huge coincidence (or not!) but as you say, it's a good idea to run it all past your doctor.
I was prescribed Altace years ago and developed diarrhea so severe everyone was alarmed. No doctor ever considered that it might be the Altace even though I kept saying "this all started with this drug".
Had a colonoscopy and full GI workup and THEN they said, "oh, gee, it must be the Altace"
After discontinuing the med I was right as rain within a week. Now on Diovan for 8 years, no side effects, and beautiful BP control.
So , good luck, let us know how it goes...
