My left arm has been aching and feeling weak last two days..it comes and goes..should i worry?..im thirty two female

Have it checked out: Left arm discomfort can be due to a lot of causes including heart disease, pinched nerve from the neck, carpal tunnel syndrome, a neurological cause, among others.Have this checked out by ur doc, who can examine u&find cause.If, however, one is a diabetic, smokes, has very high cholesterol, or has family members who had heart attacks early, and the discomfort is bad and lasts more than 10 min, then call 911.
