I had open heart surgery four years ago to replace the ascending aorta which had 2 chronic dissections and to replace the aortic valve. The surgery went fine and I recovered nicely. The scar was nice and flat and not that noticeable. In the past couple months I've been experiencing a lot of heartburn, acid reflux, and chest pain. I went to the ER in October and they assured me that it was just GERD. But now I have a hard lump about the size of a large marble on my sternum. My primary care doctor has referred me to a general surgeon but I'm wondering if I should see my heart surgeon rather than a general surgeon. Could this be related to the heart surgery? Can you get lumps of scar tissue that cause chest pain 4 years after surgery? I'm scheduled to see the general surgeon on Thursday. Thanks!
