Thank you for your question.
The kind of pain you have described is typical of degeneration at the craniocervical junction. Atlantoaxial arthritis
can lead to pain at the base of head that particularly worsens on head movements. This pain is not uncommon in elderly individuals. A CT scan of the cervical spine
with inclusion of craniocervical junction can diagnose this. Treatment of this is pain killers, local analgesic
application and local heat. Image guided steroid
injections can be done by aan expert specialist.
Wish you the best.
