question: I am 49 and have a heart murmur that has not impeded any activity in the past. Yesterday after a weekend of working on my house in the hot sun with no breaks for food and water, I woke up with a pain in my heart when I rolled over on my back. It subsided when I sat up, but I was pretty exhausted and slept all day. I felt fine by the evening. This morning when I woke up I felt a slight pain (not as bad as yesterday) again relieved when I sit up. I have a heart vitamin with coenzyme Q10, resveratol in it. I took one yesterday plus one aspirin. I have stayed home again for rest. I have no insurance right now. Recommendations?
