Allergies or tmj or both!

about 2 weeks ago I developed a major problem while eating lunch. I was eating some steak and started having bad pain in my jaw and ears. This occurred twice in a few days. Ever since I have seemed stuffy nosed and my ears are popping constantly and I sound stopped up and my jaw then and now does not want to open good. Not to mention I have a sore throat more on with this then off and feel a clump in my throat. Has anyone else experienced this pain upon chewing something like that? I do not think the popping in the ears and the pain upon chewing steak and the inability to open my mouth good would be reflux.

It may be different for everyone but I have both seasonal allergies and TMJ (confirmed by X-ray). For me if its allergies chewing something chewy (like tootsie rolls) relieves the preasure and head ache. If its TMJ my jaw gets stffer if I chew something chewy. Mucinex, steam and chewing will provide lasting relief for the allergy headache-nothing seems to help the TMJ ones not even Tylenol.
