Hi, I consulted heart & lung doctor and ran into list of test(ECG, ECHO, TMT, Lipid Profile, Chest xRay, CT Scan for Chest) and every tests are normal. I consulted another doctor for second opinion and he suggested me to change my seating position while I work(used to work in lying position). He asked me to do Vitamin D,B12, Folic Acid test and did that as well. Now report shows Vitamin D 25 Hydroxy is "insufficiency". Will this would be the problem of my chest pain? Chest pain can be tolerable, feel like sharp pain on any one side of the chest. Attached CT scan summary & blood test report
