I do hope in the long run these issues you have will go away. For me it seems that by the time I finally was getting used to living with the nerve aggravation it all finally subsided.
Now, because I'm a guy and men generally are not wired correctly, I decided to get back to playing the Bugle after a twenty year absence. More to the point it was after my mandible was rebuilt three years ago that I thought I could do this. Instantly I was met with old nerve pain on the lips, cheeks, and neck. After about a year currently the nerve pain has more or less gone away even though I can only play three notes so far. I need five for Taps and six for Reveille but I keep at it and the pain has now gone away. Not sure if the nerve damage to my mouth will ever allow me to play well again. It's good exercise and there is some merit to fighting pain with pain.
Not sure if I am telling you anything meaningful here. Perhaps just hope that in time this may all get better. In the mean time it is okay to cry into your pillow at night as I did many times. Just don't give up trying.
