MSE pain

I got my MSE installed 3 days ago and I’m in literal hell.

to help the split they also did a piezo cut, and the swelling from that is insane. my top lip, and all around my nose is so stretched out my face looks absolutley distorted. the oral surgeon says it’s normal, but I have never had swelling that bad. I can’t even open my mouth normal because it’s so swollen. my whole mouth hurts. my tongue is getting cut up on the apllliance. I don’t even want to attempt to eat anymore because it’s not worth the pain. Talking is hard and I have a lisp. I just want it out. does it get better or??
