for your response. I have not had any pain on exertion, but I know it's a good idea anyway to get my heart checked out. Someone told me that nytroglycerin can also relax esophagus spasms, so that it could still help the pain I experience ,yet still not have a heart problem. I guess it's best to find out and not guess. I think I am also a bit depressed. I will be ok though.
