Occasionally I  will waken from a dead sleep with a squeezing feeling in my chest.  No pain, but I feel momentarily short of breath.  I went to a Dr. and had stress test and nuclear test but they said everything was fine.  I had one last night for the first time in  2 years.  The only thing different was I drank a pint of beer a couple of hrs before bed.  This scare me. What could it be?
Hello, Most probably a gastritis and reflux. Do you also have upper abdominal pain, nausea, bloating, burping, increase in pain on food, sour water feeling in throat or chest burning, these are the other symptoms and may be associated?  You should avoid fatty, oily and spicy diet. Have some walk after having food instead of taking rest. Have multiple small meals instead of heavy meals. Have regular sleep habits and avoid stress. Lots of green leafy vegetables, fruits. Avoid smoking and alcohol if any. You can get prescribed tab Pan DSR 40 mg or omeprazole risperidone combination before breakfast once a day for 2 weeks. If not adequately relieved, then you should add SYR sacral O or genus two teaspoon three times a day for a week. Hope this helps you and get back if you have any doubts.
