Thank you for posting your query.
The pain could be trigeminal neuralgia
(TN). However, I agree with you that typically, the pain is episodic in TN. So, in your case, it could be called as atypical TN. I would recommend doing an MRI
scan of the brain, to find out any underlying cause for the TN.
Please get back if you require any additional information.
