Your pain in the chest is not related to the harvested graft. It is most likely related to the open chest operation (sternotomy). Unfortunately, it is often difficult to treat and I would not recommend taking any NSAID's (Ibuprofen) for long periods of time because they counteract the beneficial effects of ASA. Tylenol is ok as long as you don't consume large quantities of alcohol and your liver is healthy (sounds like it is because you are taking crestor). Physical therapy can often be helpful and I would strongly recommend that. Of course, taking easy with all this physical activity would probably help with your pain but it sounds like you enjoy it too much to give it up and I support that, plus it's good for your heart.
