I am 44 and getting muscle cramps in both lower back sides,upper back under armpits also what feels like the heart area and stomach area everywhere I guess, mental confusion rashes,bloating pink eye and headaches every day. I take meds every day for pain like fioricet,Prozac, and xanax I've taken these for many years.I'm not sure what this could be but I do also take omeprazole 20 mg.every other day just to keep the acid reflux down.how do you explain to a doctor all the problems I could keep on naming them maybe its just getting old.BUT I DOUBT IT
