What causes high heart rate and muscle pain?
Patient: I am age 53 male  and exercise daily.  My normal heart rate is in the mid 50's.  in the last few days, my resting heart beat has jumped to near 70-75 per minute.  I have also been experiencing some muscle pains in arms , shoulders , and legs.  No chest pains.  Should I be concerned?   Gary Doctor: Hi,It seems like some general disease, maybe you have caught cold or something similar.I would advise you to take temperature and have blood tests done, to check if there is any change, like high WBCs.Wishing you good healthRegards,
