Sore scratchy pain in the lower jaw end.

I have right ear pain, lower jaw pain with swelling for more than a month.It started off after I chew a lot. Chewed soft foods more than usual.Next day heard some big snapping sound in the jaw.Then jaw pain and swelling started.Thought it's because of sinus. Went to dr,got antibiotics for sinus and ear Infection. But the swelling and jaw pain still there.Its like constant sore,scratching kind of pain throughout day/night.went to dentist last week and had x-ray.He couldn't find anything. What is the issue?Swelling didn't reduce even after taking anti inflammatory.Pain and swelling Same for a month. Hurts to touch under the ear at the jaw end. Mouth hurts to open big and hear clicking sound when opening mouth.is anything related to jaw bone?Any damage to jaw bone? I am so worried.went to multiple doctors during this pandemic and no solution yet. Having the same pain and swelling. Dentist said might have crack and sensitivity on lower first molar.does it cause jaw swelling?jaw issue?help.
