Hello~I am sorry you are having this pain, that takes all the enjoyment out of life.
From your description, it appears to me like you have an issue with your TMJ (Temporomandibular Joint)You could have dislocated it while you mouth was open so long during the extraction. I would certainly ask you dentist about this. There are devices a person can wear and also treatments for it, such as an anti-inflammatory.
I hope you feel better soon.
