Hi, I am 76 years old and have a history of hypertension for 15 years. I am controlling high blood pressure by taking prinzide. I am also controlling my high cholesterol by taking zocor. I exercise and regularly visit my cardiologist. I visited him recently, had an ekg done and was told it was good.

Several days after that visit, I experienced heart pain that lasted for many hours (about 10 hrs, started in the evening and didn't stop all night). It wasn't sharp, but it was significant. The pain stopped in the morning. The day before it happened I walked a lot and was feeling very tired. Should I go to the cardiologist or should I have gone to er? Why do I experience the pain when my ekg is good? Thank you very much for any information you can offer.
