Lower jaw pain under the ear, neck pain.

I have lower jaw pain,ear pain with mild had swelling for more than 2 months. I didn't injure anywhere. Had sinus infection,took antibiotics.Sinus cleared up, but the jaw pain,ear pain didn't subside.Went to ENT and did Endo.No Infection in sinus and ear.He was not sure why I have swelling in jaw,pain under the ear. Went to dentist and he said might be TMJ or upper WT issue or minor crack on lower molar.No definite answer.I extracted my upper WT 2 weeks back. Still the same symptoms persist.Even before the extraction,I had neck pain. That side of the neck is sore and tender and mild swelling. It hurts to touch under the ear and neck. Continuous sore pain. Why it hurts to touch under the ear (jaw end) and neck? It feels like swollen.I do have post nasal drip, green/white discharge. Feel so tight in throat sometimes.It feels sore inside the ear after I wake up and get clogged in the day.Feel sore inside the ear, under the ear, neck,top right side of head. lymph nodes or glands issue?
