I ve been having muscle spasms for a couple of years now. I had a cigarette after using a quit smoking aid today and I passed out, I fell off my chair and didn t come to until my brother checked my heart rate. He s got lupus and was worried I had, had a seizure. My question is, if I m having muscle spasms, usually in my hand/wrist or arm, ( though they have occurred in my face and right eye) and they seem to stay on my left side, what could be wrong?
