Pmma shots - is there a way to check if everythings ok down there?

I got Pmma shots in my butt (i pray they didnt use something else) about 8 years ago when i was making a ton of poor life choices. Recently ive been getting some pain in the right which sometimes goes down my leg. Might be sciatica or something unrelated. After reading a bunch of horror stories of butt injections gone wrong i wanted to see if theres a way to check if everyrhings ok down there as I cant afford to remove them right now. Please advise !
