So I'm at that point where I'm going to get TMJ treatment with daytime splint and some sort of sleep apnea jaw positioning device for night time. They also work with airway/breathing and seem really knowledgeable. Its $7,000. Has anyone had anything similar and had success?

Been 2 years with TMJ. Bad jaw joint cracking. My jaw joint has like a dent in it. Hurts a lot and getting worse. Bad neck pain, really bad ear pain (hyperacusis and tinnitus). Everything on the left side. I can't afford it but I'll pay it off eventually. I feel like not doing anything is making it worse everyday. Any encouraging success stories, please share. Right move going forward with treatment?
