I sometimes have pain in my chest. I feels like my heart, like there is a problem with my heart. It also felt, this only occurred once but it made me nervous. I was breathing okay but felt like something was wrong with my heart maybe the valve inside the heart. I got a sensation as though there was more space than before. My older sister passed away in April 2011 suddenly at age 48 due to heart failure. It was sudden no warning signs. I did get checked out but according to the doctors everything looked fine.
Hello, Have you undergone ECG and treadmill test as well. If treadmill test is also normal then no need to worry.  It can be due to gastritis and reflux disease. 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.
