I've been dealing with chest pain for quite a while now, and I just found out from an ECG that everything's normal. The pain isn't in one specific spot; sometimes it's on the left side, right side, or even lower down. Im starting to think it might be muscle-related. Is there something specific I can take for muscle pain? On top of that, I've noticed I get short of breath easily. I've been really inactive the past few months, barely moving at all, so Im wondering if this lack of exercise could be causing my stamina to drop and making me feel breathless. Could that be the case?
