I Am A 60-year Old Male In Good General Health.

I am a 60-year old male in good general health. Recently (within the last month) I strsted expeiencing mild angina and related chest area pain while at rest, combined with general fatigue, minor anxiety, and trouble sleeping. When the symptoms first occurred, I went to the hospital ER and they worked me up for a possible heart attack. They said everything looked fine with my heart (EKG, etc.), but I stayed overnight for observation. I passed a stress test the next morning and felt fine for about three weeks - no symptoms. Now I am having the same symptoms again. It's more discomfort than actual pain, but it can last for a couple days or so. I have a regular doctor's appointment in 3 days. Is there anything I should do until them?
