If I'm correct cold sweats are feelings of heat and then chills? Anyway, I have been having this symptom for a few months. Is this indicative of a possible heart problem. I don't have chest pains. I don't have shortness of breath and I don't feel weak, except that I do feel tired at times, but I guess we all do. I do have, at times, elevated blood pressure and a rapid pulse, but more often than not by b/p is pretty decent. Does this sound like it could be heart related. Had an EKG twice which was fine. Also had blood test for homocystine level, which was fine too. Any ideas? Thanks for reply.
