I ve been experiencing a strange dull ache in my left arm. Initially it was just on my wrist around the carpal tunnel area, but now my entire arm feels void of energy. When I leave my arm to hang by my side it soon feels like there is a pressure build up and my veins stand out more than they usually would. Other than feeling run down I also have a slight chest pain that comes and goes, but I m not sure whether that is due to anxiety. Any help would be very much appreciated. Thank you for your time.
