I had a very similar thing in January. But my pain only started in the afternoons & was very intense around my left ear & along the jaw. 3 Drs & a hospital visit couldn’t find a problem. A 2nd stronger round of antibiotics did help eventually.
Do you have any little sores that have come up on the same side?
A ENT specialist diagnosed mine as shingles, unfortunately it was too late to have the necessary needle for it.
I Still get occasional pain there now. That can last 4-6 months after the occurrence called post neuralgia.......
good idea to check out by trace18. My husband had something similar and he had cellulitis from staph on his skin. Have you been to an ENT?
