Recently I have had a sharp pain in the wrist , not in the joint but seemingly in the blood vessels or tendons right before the wrist. It then jumps from there to underneath the left breast & throbs a few counts there. I have no difficulty breathing , run/wallk often, am a healthy 50 year old woman 5 5 at about 118 lb.s. I used to lift more weights at the gym but had to let my membership go, but am called upon to move file boxes at work fairly often.
