Hello. I am a 17 year old male. Recently, (within the last 5 years) I have begun to experience issues with my jaw (this pertains to my hearing). These issues began after I was punched in the jaw. My jaw is constantly popping, catching and locking. This is extremely painful. I've been to the dentist and he told me I possibly have TMJ. Just recently, (within a week) I was eating and my jaw caught and produced one of the worst pains i'd ever felt. Seeing as i'd felt this before, it wasn't much cause for concern. But 20 minutes later I noticed when I smile or laugh (stretching my jaw in general), the pressure deep in my left ear builds up. As the pressure gets more intense, the hearing in my ear slowly fades. Are the two related and is there anything I can do to fix it?
