I had a pacemaker place in my chest on 2 May 2011.  My heart was beating too slow; 35 etc.  Since, a keloid has formed over the surgery spot and it itches and I have a stinging pain with it or on it. Is it dangerous to put something on it to heal it, since it is close to my heart?I am 68 years old, 59, 274lbs; I have high blood pressure and is on medication for it; recently had a blood clot behind my left knee as I broke my left ankle last Aug 2010; but the clot is gone none.
When was the pacemaker done? It's ok to apply antibiotic cream over the pacemaker site. But if keloid has formed it won't help much.
