Jaw pain

Hey ya’ll!

So recently i have been having jaw pain on the right side only right where both jaws meet, kinda at the hinge and sometimes it hurts to open/close my mouth. It lasts for like a week or two and then disappears for a bit before coming back. My family thinks it’s just how i sleep (teeth grinding which i dont think i do) or they think it’s because my teeth have been shifting due to not wearing retainers which they think once i start again it will solve the problem.

I did some searching online and it doesn’t seem like it’s anything too crazy, they said it could be tmj which some people usually it goes away for them.

Any tips on helping reduced the pain? Should i go into my clinic? Do i try my retainers again? Any thoughts or tips would be great!
