Lower jaw pain under ear and neck pain.

I have right lower jaw pain exactly under the ear, lower jaw , ear pain for more than 2 months. This started after I chew some meal more than usual and next day I heard a pop in the jaw and jaw pain, seeking started that evening..went to different specialists. Went to ENT amd he did Endo. No Infection in sinus and ear. No wax buildup. I went to dentist and he said I might have a tooth crack/fracture or TMJ issue. I couldn't get proper definite answer from the dentist if it's TMJ or tooth crack. Whether TMJD cause neck pain? After a month of jaw pain, my side of the neck is swollen and very painful..like sore pain for past 3 weeks. I have pain on top right side of the head above ear. It's very sore. It hurts to touch exactly under the ear where the jaw ends. It's paining from day 1 for past 2 and a half months. Whether this is tooth or sinus or TMJD issue? My ear is clogged and feel fullness for 2 months. I have sore pain inside the ear, side of the neck and under the ear. Is it TMJD?
