Is it neuralgia or TMJ? Anything else?

My symptoms are,severe burning sore pain in the lower jaw under earlobe and on the side of the neck since may. Mild Swelling in the lower jaw and neck. I have small pea size lump on the neck along with mild swelling. Sore ear pain with mild swelling.i went to ENT and no Infection in ear and sinus. I went to dentist and no infection in any tooth. He told me to extract upper wisdom tooth and I did that 2 months back and same symptoms still. dentist said I might have tooth fracture on lower first molar and told me to RCT or extract it. But crack is not visible on x-ray and cbct scan. So he is guessing that might be the reason. i have sore pain in the jaw, neck and top of head. I have burning pain which is very severe. I do hear clicking sound in the jaw when I open the mouth. does it indicates tmjd or any nerve issue? I hear some ringing sound in my ear whenever fan is on and while lying down. does a tooth crack could be a reason or anything else? it hurts to touch under the earlobe,neck
