I started having chest pains and burping in august 2017. I had an ecg ,echo, thyroid test (liver and pancreas test also) All came normal. Doctor said its anxiety since I am preparing for competitive examination. My chest pains have reduced but my burping has not stop. And now since january 2018 I am having pain in my left arm that suddenly comes and goes. I am very paranoid and keep checking google for symptom of heart attack and stroke. I even measure my bp 2 times a day just to be sure. This has also started interfering in my studies and my parents are also very concerned as all doctor says I am fine. My weight has also reduced due to this and my father thinks that going to doctor would be to waist time. What to do?
