How to know if I have neuralgia. Tn?

I have constant burning pain under ear in the jaw since may. It started suddenly one day when I was chewing my food more than usual. Next day, heard a pop in jaw, jaw pain started with mild swelling. Still the same pain. It radiates to neck in July. Constant burning in side of the neck since July. Ear pain, ringing in ears, hearing some soft music humming sound in ear,sore pain on top of head on one spot above the ear. These symptoms since August. Went to dentist and he told me to extract upper wisdom tooth, do root canal on lower molar. Still same symptoms. Ent checked for sinus infection through Endo and no infection. He want me to do CT scan for sinus. I went to tmj specialist and he told me it's muscle tightness and jaw joint issues. My dentist want me to check if it's eagle syndrome or trigeminal neuralgia. Does my symptoms indicate TN? Does it affect the neck area too? My neck is tight and stiff. I have constant feel of something stuck in throat. I am able to swallow food. TN??
