Hello,
You are experiencing pain at the back and chest. It is a weird
stabbing pain. When you change position you can't breath due to hurt and it also hurts when you sneeze or cough. Your symptoms are indicative of
costochondritis, a benign inflammation of the upper costochondral and sternocostal joints, may radiate down the scapula. You can take naproxen or
Combiflam, one SOS when pain. You can also apply pain relieving sprays and
ointments. Gentle massage may help. Get connected to a physical therapist, stretch exercises, walking and massage will help you get better.
Other medical factors that may cause similar symptoms are nerve impingement, stress- strain of the muscles / nerves during exercise or lifting heavy weight. However, you are suggested to get clinically examined by an Orthopedics, get imaging tests done to detect
fracture, tendon /ligament tear or nerve entrapment or any other pathology causing you symptoms. You will be treated accordingly. Stay away from addictions if any.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
