I have been taking zonagram for 3 years for seizures since my stroke. Since being on the zonagram I always felt " not right " shitty and more shitty. Last year I told my Nero I was having leg pain and arm pain and I felt general feeling of shittiness . They took my zonagram levels and said I was fine and wanted to add on another anti seizure med. I didn't take that crap. Last year I needed an antibiotic so I got sulfa and after one dose I descovered I was highly allergic- I never even thought about telling my Nero . Tonight while I was googling leg pain ( 1000 reasons of course) I typed in . Could zonagram be giving me burning sever leg pain , getting worse over time . It popped up that zonagram is sulfa med with anti - convulsant effects . I tell my husband " I swear this shit is killing me " I am fatigued, dizzy , angey , sad and I have anxiety, can't sleep . My blood pressure is very low , brain fog .. I need to know if anyone has had similar experiences and can I go off cold turkey because I am afraid this shit is killing me with my sulfa allergy .. Btw. I tried calling my Nero tonight - nothing !!! I didn't take my pills . Sulfa makes me throat swell and I get hives on my body - wth. I scared I have been poisoning myself. ????
