Occasionally I experienced the following symptoms: pain begins on the left side of my chest, then a burning sensation radiates up the middle of my chest to my throat and then i feel pain across my lower jaw. After this the pain seems to move to my sternum area and then subsides. I may experience 2-3 episodes a year, and recently had 2 in the last 2 months, with the most recent one last night. The last 2 times, it happened during the night. A few weeks ago I had a simple stress test and it was recommended that I have a nuclear stress test. I had an EKG which was normal. Should I be concerned that this may be a heart issue or does it sound more like indigestion? Im a 59 year old woman.
