Suggest Treatment For Pain In Lower Neck And Crawling Sensation On Upper Chest

hi dr,
I dont know where to start from as I have given all hope of recuperating. i am 28 years old, weighs 75 kg and hail from india. my prob started 5 years ago. I feel constant pain (sometimes severe) in the left side of neck particularly at the bottom of neck..along with this i feel pain on the left side of the chest closer to arm pit..i always feel heaviness in this area and sensation like something crawling and even ripple like effect. i think this is the root cause of the pain that does up in the nect area and also in hand and toward left leg. i got the ct scan done for neck but it was normal, i also underwent neck xray that suggested mild osteoporosis and no sign of cervical defect. i have already consumes so many allopathic medicines for muscle prob and medicines like pregabalin, mecobalin that give temp relive but no much effect. i even took physiotherapy sitting but it did not yield much result and benefit. many times dr are not able to diagnose the root cause and straightaway jump to conclusion that it's either spondilytis or spasm but i think it severe as all possible treatment turning futile. this has greatly effected my daily lift as when it pains i find hard to concentrate, my memory gets effected and feel sluggish.. i think there is some nerve prob that is originating from left chest and going upward that causing entire disturbance. when i touch the left side of neck and chest when it pains i find some stiffness; i have visited ortho, muscoskeletal but dont know who can cure me.it has really put my life on back seat.

thanks for assisting!
