I had aortic valve replacement surgery on June 12th, 2014. I am 4 weeks into cardiac rehab and doing fairly well. I have had some issues with PVC's but nothing really big. I am still experiencing pain in the upper portion of my chest and of course my breast "skin" hurts to the touch. I noticed that the right side of my collar bone seems to be higher than the left. I actually don't really feel the left side. Is this normal?
