Hello and hope you are doing well.
Your symptoms of discomfort on lying down and lack of sleep could all be attributed to GERD, (Gastro Esophageal Reflux Disease), where the acid contents of the stomach come up into the esophagus. You could try life style measures. Take frequent small meals. Eat dinner about two hours before sleeping. Elevate the head end of the bed. Keep a food diary and note down what aggravates your symptoms and avoid them. Ensure to maintain optimum weight by regular exercise. Avoid non steroidal anti inflammatory medications NSAID's, quit smoking, eliminate alcohol and reduce stress levels. These measures need to be practiced long term for results.
Hope this helped and do keep us posted.
From one symptom you are having you cannot diagnose yourself thinking you are having a heart disease. The medication he gave you said: “not to take it if you have any heart disease.” You don’t, the test said. Why don’t you believe it?
“That cannot be true but he would not listen.” you said
I had Congestive Heart Failure, i much more symptom involved than what you described. So just relax. If you don’t believe to this dr. go and get another one, but you can save your time by believing to this one.
It could be so many other things then heart disease. I would take what he gave you and see what happen. If you overweight, smoke, drink, etc. …or drink energy drink, caffeine, you should stop and look into those habits and change it for only healthy food and drink.
