I had my first pacemaker 1996 not the best experience. Had problems with right arm.Went for therapy and cortizone shot helped. In 2004 my lead was fractured while i was getting out of my car for work. The funnies nosie which I cant explain . I was very active so probably the lead got worned .I went to my doctor.'. went for test and referred me to a dr. in Albany. It was scary due to the risk involved. I had both leads replaces and a new pacemaker on my same right side . Its been 3 year and never had a problem. Dr. did a beauful job. I feel better then before and no shoulder and arm problem exist after surgery. I wanted you to know i had a good experience . I know its a big decision to make . Not all doctors. will remove and replace youll need to discuss this with them .Hope input will help.
