Where in ALABAMA do you live? There are EXCELLENT Heart Centers in Huntsville and Birmingham. I'm not familiar with Heart care in South Alabama but I know they do have hospitals that attend to heart problems.
With SHARP PAINS in your chest, you should be seen ASAP. Is there a MAJOR Emergency Room nearby? If so, GO THERE. If the ER Doc believes it is heart related he will get a Cardiologist to see you IMMEDIATELY.
