Brief Answer:
Looks like trigeminal nuerlagia, but needs further evaluation

Detailed Answer:
Hi and Welcome to "Ask a Doctor" service. I have read your question and here is my advice.
Sorry to hear about how you have been suffering lately. The pain may have many causes and would need a detailed assessment but it looks more like trigeminal nuerelgia. Trigeminal neuralgia is inflammation in one nerve in the face. It causes very severe sharp, or throbing pain. The pain is mostly in brief episodes and may come like electric shocks. Pain is precipitated by chewing, brushing etc. Certain drugs may be advised and help alot, once this is confirmed.
Another possible cause is problem in the joint at the temple, (TMJ) specially omif opening of mouth is very painful.
Sinus infection is another possible cause, that is more likely if pain is persistent on the cheek area, and if the cheek area is swollen, or painful to touch. Or if you have recently had a flue or blocked nose.


So there are few possibilities, but a pain that does not respond to simple analgesia and persists should be investigated. Mostly it's not for any serious cause, but need evaluations as different drugs are used for the management, specially as the likely cause being trigeminal nuerlgia. So I understand that examinations is necessary and may need few tests like xray or even scans just to be sure that every thing is fine.
So for the time you may use heat applications, along with the pain medicines for some relief, but you need to see your doctor for proper assessment and management.
Hope this answer help you understand your querry. Please feel free to ask if you have any further questions or concerns. I will be glad to answer your questions.
Kind Regards Dr Mahboob Ur Rahman
