Since my pace maker, difib implant, I started using
metoprolol succ er. When we changed to bisoprolol I have experienced ankle pain, now severe knee pain, and pain in implant area when trying to do bench presses. We have changed back to metoprolol starting today. Befeore implant I could run 25 miles a week without pain. Ater implant abot 10 -15 miles a week, less miles, slower pace with added days to rest in between. This is the first time I am experiencing pain ever. what should I do?.
