Hello, I have studied your case. Most probable reason for your symptoms could be postural problem as you may be sitting for long time and may be sitting on computer for long time. Neck and chest pain may be arising from back [spine] When such patient comes to my hospital we usually take x ray spine or if required MRI to see for any nerve compression. Medication like methylcobalamine with muscle relaxant and analgesic will reduce pain; you can take them consulting your treating doctor. Some exercises which can be done after pain has reduced include- Spine extension exercises, lying on your stomach flat lift leg 6 inches from ground, do it for other leg. Now lift both hand and leg simultaneously, 6 inch off the ground and stay Position for around 10 breathes. Core stabilizing spine exercises will help. You may consult physiotherapist for further guidance. He may start TENS, or ultrasound which is helpful in your case. I will advise to check your vit B12 and vit D3 level.
