It's my opinion that when you go looking for trouble, you'll often find it. Drug companies have to list all POTENTIAL side-effects of meds to cover their butts legally. Since your average person has little knowledge of the incidence of a particular side-effect, they might cause themselves unnecessary panic by trying to self-diagnose low risk "shots in the dark." As WC pointed out, pharmacists are trained to identify problems of the nature you're describing...& it goes without saying, that pdocs are, as well. If you have any doubts, call your pharmacist, or try to get through to your pdoc. It sounds like you're really freaking out.
