I am having nausea for at least two weeks now.tried motion sickness pills, pep-to bismol, etc. feeling weak at times. Also get rush of heat while nauseous.. Have valve regurgitation but not serious. Take water pills because of the valves and I do take water pills for swelling. Have reduced them to every other day since nauseous. The above over the counter drugs have worked somewhat. Have a little pressure in my chest. I have just seen cardiologist and I am ok.
