Persistent pain from wearing retainer at night

[aguy1010]

I'm an adult, 24, who had to get braces to correct some jaw alignment issues as I had TMJ pain. I got the braces off about 7 months ago and its still been a bit of a struggle, although its gotten better over time, that when I wear my invisalign retainer at night it causes some jaw pain (specifically TMJ joint pain, which is, I guess, actually above the jaw) the next day (the wire retainer was even worse). I've tried everything I can think of but it still persists and it seems like if I don't wear the retainer almost every night my teeth start to shift which causes even more problems.

I'm curious if anyone else has a similar problem and if you have any suggestions for stopping the pain (it is in my TMJ joints)
