To those who gave me advice on my daughter's problem with the pacemaker. She had two procedures to get rid of the clots, they found one that was so old that they could'nt displace it. Her arm still hurts quite a bit. She has a compression sleeve to wear. She is on coumadin. New veins started to form in her arm, which one's body sometimes does when a vein is no functional due to the old clot. I never heard of that. The heart doctor has revised the office guidlines, when patient come back to complain of pain in the arm. They will no long tell them to go home and put heat on them, will suggest ultrasound. So all in all, the health problem is slowly improving.
