My left arm and hand swell and turn red and even purplish after I had an icd implant. I ve been to the mayo clinic and they weren t alarmed. I ve had it checked for clots and nothing. They did say that I was missing a vein in my left arm. I am 45 and I am extremely active. I run/jog daily, coach cross country, bike, teach, and try to stay active. After I lift weights, run, or even shower, my arm swells
