Chest pain; Myocardial bridge. Day, pls!

I am 39 years old, male,. Around 20 years back i was heavily into sports. In May last year an angiogram was done which was normal but it showed a myocardial bridge in mid LAD causing a 30% systolic narrowing. Dr said its nothing and its pretty normal. But i still have the pain sometimes in chest and in the left arm. the pain always starts in the evening and lasts till night. happens in phases 10 days followed by no pain for a month or so and then again comes back. I saw a gastroentologist also who opined that i am suffering from GERD , did an upper GI endoscopy which was normal except for HPylori infection. Put me on pantoprazole. though things have improved but i still get pain in the chest The Dr said since i get anxious always it aggravates the pain and the GERD. The cardiac’s say angio is done and its clear and that is conclusive and gold standard test. I have started doing exercise and yoga diet modification, lost around 5 kgs wgt,cheut down smoking to only one per day, pls
