I Feel As If The Skin Inside My Mouth Is

I feel as if the skin inside my mouth is deteriorating. For example, if I move my tongue around the top layer of teeth, the tip of my tongue reaches up so high that it will move my nose on the outside. If I move it to the left or right, I have maybe a little over half an inch of tissue inside my mouth that is connected from where the orbital wall on the bottom of my eye socket is. There has never been any pain, swelling or bleeding, but I am convinced that it has been slowly getting worse. I used to use cocaine heavily, in winter of 2013 and have abstained since March 2014, and I know this can affect mid facial deterioration. However, I don't know why it seems to be getting worse, how far up does this skin connection usually go?
