Since few days I have been marking that I am having pain mainly in my left side back,sometimes in fingers,left arm too. The pain is not intense rather it's a pinching one . It comes and goes of its own . Few months ago my thyroid level was at higher side i .e. 7.20 . I was taking medication for it. Now I am not taking any medicines. Please let me know whether this Angina, or related to heart or in near future if any heart related problems might arise . Or is it due to thyroid . Kindly help me .
