Thanks for writing to us.
I am Dr. Vaibhav Gandhi, I am Orthopaedic surgeon
and spine specialist.
I have studied your case. It appears to be an occupation[excessive computer use] related problem. Other most likely reason could be cervical disc.
The cause of frequent problem -this kind of pain is due to compression of spinal nerve
because of spinal disc bulge[ disc-is a soft cushion between two vertebrae]. Nerve compression lead to radiating pain
[along chest or arm and hand ], which aggravated on long time sitting in same particular position.
Here are my other useful suggestions for neck strengthening :
Avoid lifting weights , Avoid excessive stress
on neck muscles
Sit with a support on your neck and back.
Take break every half hour while at office. Try to do some stretches and joint movements .
If the above do not help, you may need to see a Physiotherapist
Check your vit B12 level and vit D3 level through blood test
If such patient come to my clinic I will investigate in the form of - X ray chest and spine and if needed, MRI spine and management accordingly.
Hope I answered your questions.
