I have been experiencing chest discomfort for over 5 months. Pain is extremely dull and on both side of the chest, it feels like poking pain and lasts barely 5-10 seconds in one place. I have no problem in moving around and doing my every day activities however I have mild pain in my arms and neck since last 10 days now. My blood works, including lipid profile,B12,D3, chest X ray, ECG,echocardiography are all normal. ESR is 38 and haemoglobin is at 11. There is no pain in my chest since past 10 days but I am worried about the pain in my arm. What could it be? I've spoken to 7-8 doctors and all of them suspect musculoskeletal issues. Please look into the matter. Below I've attached my echo report.
