I get why you are feeling claustrophobic because your natural movements are restricted. I had the entire length and undrside of my tongue replaced as well - I think the adhesions are because you have two raw surfaces touching so it's natural they would want to heal together - with a graft you wouldn't have that problem because there's no open wound area. Moving it as much as possible despite the pain should help. It's too bad there wasn't a non porous mouth guard that you could use to keep the two surfaces separate - it would have to be sterile though which is hard to do - during the day it's not so bad - but those inactive periods at night are the hard times. My thickness of the area removed was 14 times your thickness. It was 1.4 cm deep - I think any graft he would do on you would be very superficial. More like a simple layer if skin, but that's still very involved. The swelling will decrease once you heal. It won't stay like that. Hopefully you're past all of this and just need to heal. Sorry you've ended up With bronchitis.. Not fun. Take care and rest up! It helps with the healing as you know.
