Hopes, sorry to hear of your problems. When I have symptoms that are frustrating, I do an inventory of all the meds I take. I look for contraindications amongst them. Especially when I have gastro difficulties. So many meds alone and mixes of meds cause changes within us.
I think you take a CCB called Norvasc, don't you? A few years ago, CCBs were not considered "just great" by many cardiologist, probably due to some clinical studies that came out. Since that time, other studies have shown well for CCBs. Anyway it is a heavy duty med. as you already know. I think you said that you take a small dose for artery spasms. Maybe you could quiz your doctor and see if this med could be bothering you. You also know to never stop a medicine without your doc's approval. (had to say that :) ) I abruptly stopped a beta blocker once and probably paid the price. I didn't know not to do that.....
