i am a 30 yr old male with boderline high bp and cholestrol. the last few days i am getting a sharp pain on the left side of my chest that lasts for 5 seconds then stops. is this angina or could it be heart disease?? the pain comes and goes thruout the day? what are the kinds of pains u get with a heart attack or heart disease. i have got pvc's before but never a sharp pain like this. i do have mitral valve prolapse, and my cardoligist cant see me til jan 5th? what do i do?? i also do a mile on the treadmill about 3-4 days a week i dont get pain when im on it but the pain did start about a hald hour after i ran on it yesterday.
