I am a 23 year old male suffering from pain in left side of the back neck, shoulders and a specific spot (like a nerve) in the back chest. Its been paining for over a year. Sometimes the pain passes like a shock to the chest, left hand, finger tips (like pricking). Some days pain is severe. I have consulted one or two doctors and had some medicines, one of the doctor said a nerve has been pulled while lifting weight. But even after I took the medicines I am not relieved from the pain. Please advice me what to do next.
