A catch/sprain in left lower jaw joint.

**URGENT** I have a horrible catch the left ear near the left jaw. I can feel the pain in the spot where upper and low joint meet.if we press ear tragus part..corresponding to the bone behind the extreme last molar on the left lower jaw. I feel pain when chewing semi solid food as feel some terrible catch in the the jawbone,all of a sudden I have this catch. the pain has spread to my left ear/throat headache on left side with eyepain..I have a "pain lump" also below left ear and jaw section. Pls tell me how to overcome this catch... I tried doing small jaw exercises but no use. Bcoz of this nerve/muscle around area are in pain/some flexible jaw bone got twisted Kept warm bag on ear jaw throat area too,have been applying myolaxin since many days. What should I do to give immediate relief? Any pills for this sprain/twist? Awaiting a way out of this catch.
