Chest Tightness and Upper Back Pain.

Dear Doctors, I am having constant upper back pain, chest tightness & pain for last 7 months, initially consulted ortho (Dec 2021) they said pain is bcaz of poor posture & muscle spasm. While having pain killer & physio felt better but again the next day getting same kind of pain. Visited cardiologist (Mar 2022) for fast heart rate, he took ecg, 2d echo, tmt, chest x ray & lipid profile test. Except borderline cholestrol & BP all the tests comes out normal doctor said have to reduce weight (110kg) and lifestyle changes. Taking BP pills Prolomet xl 25 ml. To get 2nd opinion visited one more cardio doctor, based on my old reports & checking me he too said everything is normal,but till today I am having same upper back pain with chest tightness & pain. Whenever trying to stand straight having shoulder tightness. Recently took ans dysfunction test, dat too comes out normal. I am totally depressed & anxious because of dis issue. Hav to do any other test or hav to see psychiatrist.
