Sacrat: Yeah, the did the enzyme test and I haven't heard the results yet. The pain radiated from the left chest (sharp and achey) up under the left arm down to the bicep (really achey). My ekg was normal, so no heart damage, but not an indicator if it was an attack or not. Doc thinks it's one of two things: Partial blockage causing mild attack or sudden onset of reflux disease. Turns out that that same nerve that flips out during a heart attack can also be "stimulated" by damage to the esophogous (sp?). So, both have teh same symptoms and he's treating me for both until Monday when I do a "stress test" on a treadmill.
