Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
It seems you have a dental problem with exposure of the sensitive root. The moment it is exposed to cold
food you feel that pain over your jaw and head as well.
Do get you teeth examined and let the dentist
lookfor some caries.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.

Wish you good health,
Dr. Srikanth Reddy M.D.
