Hi madam, in my opinion you might be having some amount cervical neuralgia
, where in prolonged working in front of computer will cause cervical nervres compression causing referred pain
If I were your treating doctor I would prescribed carbamazepine
tablet for 2 weeks along with tramadol
pain killer tablet.
This would reduce your neuralgic pain.
Along with this I would suggest neck exercises also to be done every 4 hours.
