This can
cause pain in whole of head and neck region.
Glands in neck and temporal bone pain
can be due to this. I would suggest you consult a dentist and an ENT specialist soon. Maybe your PVP can arrange it. If there is no problem in the teeth and ear, then there is a chance that you have compression of cervical spinal nerves due to overuse of computers, work involving straining of neck, canal stenosis, bone disease, spondylosis, poor posture etc.
