Hi, Thank you for providing the brief history of you. A thorough musculoskeletal assessment is advised. By your history i can understand its due to muscle weakness things are not falling into place. You pain the mid thoracic region is due to interscapular muscle spasm, Also the shoulders are aching and sore is due to trapezitis. Due to this two reasons, your symptoms are arising. Firstly you need a physical therapist who can help with Therapeutic ultrasound therapy and TENS therapy for reducing inflammation and pain in the muscles. Second - a posture correction is needed as well, as due to bad posture the strain on the muscles is high leading to abnormal symptoms. Third - need to perform exercises to strengthen the muscles of the upper back and shoulder. In my clinical practice patients complain often such symptoms and they respond well to the above mentioned plan of therapy. Regards Jay Indravadan Patel
