Jaw Popping - Is it an EDS thing?

I have this as well, but I think mine's caused by clenching my jaw. When I was a kid I used to bounce my lower jaw up and down to focus, but my mom made fun of me for it a lot. I eventually learned how to stop, but it caused me to clench my jaw all the time

I’ve been getting this too! My neurologist said it’s probably tmj and has been giving me Botox injections in my mastoid muscle when she does my migraine Botox and it’s helped a lot! It also has made me stop grinding my teeth

Yes I have tmj your jaw pops when you chew a lot or just whenever but mine also locks if I yawn to big or just because and takes forever to come back down
