How to diagnose trigeminal neuralgia?

My symptoms are, Burning and sore pain in the lower jaw under earlobe(since may) ,Mild swelling in the lower jaw (right lower), Mild swelling in side of the neck with small lump( since July),Those bump like sore spots in the neck and lower jaw under ear hurts to touch. Top side of the head above the ear hurts to touch(since July),Ringing and buzzing sound in ear while lying down(since July),Feeling of something stuck in throat and neck feels so tight (since July).My symptoms started in 3rd week of may when I was chewing some meals more than usual. Next day heard a pop in the jaw and jaw pain, swelling started. seen an ENT,OMFS, dentist. Did neck ultrasound and no abnormalities.Extracted my upper wisdom tooth and did a root Canal on lower molar as my dentist said that could be the reason. Still have the same symptoms.omfs said it might be TMJD and told me to do physical therapy. Whether this could be muscular issue or any nerve issue? Whether this looks like trigeminal neuralgia?
