Basically, ever since Freshman year of college I've been having chest pain and little bouts of "anxiety." However, last year the pain started to become more frequent, including a fast heart beats at time, which led me to several unsuccessful trips to the E.R.. I say unsuccessful because no matter how many times I've gone to the hospital or doctor they haven't been able to tell me anything. They give me an EKG, a chest x-ray, and then send me on my way. I've also been experiencing head fuzziness/headaches and strange pains in my shoulder, left hand, left thigh,and even in my fingernails and toenails. The most disconcerting part is the pain in my nails. I've had my cholesterol levels and everything checked and there doesn't seem to be any sort of concern with my numbers. I'm wondering if anyone has had these types of symptoms before or have any idea on what they might be. All help is appreciated. Thanks. (Also, my pulse can be anywhere from the high 60's to high 80's).
