It sound like you have TMJ dysfunction. It is possible you have arthritis in your jaw. I have osteoarthritis in my own jaws. I was told to use my fingers to keep myself from yawning too wide and that I would need to be on a soft diet the rest of my life. I was told I need to limit my talking on the phone and singing.
I've been wearing flat planed splint nightly, prescribed by maxillofacial specialists to try to prevent my arthritis from worsening and it seems to be helping. I still get sore from too much talking, chewing, or singing & sometimes have to take cyclic prescription ibuprofen, which I was told is the best medication for this problem.
I press them on my chin so as to try to keep from opening my mouth too wide (a doctor told me to do this). When I forget, I can often hear a pop or cra-ack! Thank you for the compliment! I think one reason why God gave to me the trials of so many physical problems is so I can help other people- which is a real privilege!
I hope you can take some steps before your own situation gets worse... it can really get bad, believe me! I wished somebody had told me with my first TMJ flare-up that I needed to make permanent eating adjustments then. When I felt better, I started eating like usual again and wound up with a permanent problem.
