Last summer I had a crown put in my back upper molar due to the dentist repeatedly messing up my tooth. It triggered a strange pain in my jaw, headache and a constant sharp pain in the back of my skull when I swallow, laugh, cough, chew...pretty much any time. I went to local medical clinic and they gave me an antibiotic and anti-inflamatory. It went away about 10 days later. It is now back as of last Monday. Not sure what to do, where to go, etc... Pharmacist says possible triad facial neuropathy.
