I don't have speech issues, but I do have swallowing issues. My uvula shrank to virtually non-existant. I have mostly gotten used to the dry mouth, but there are few things I can swallow without taking a drink. If my bites are too small, they stick in my throat and are very difficult to dislodge. If the bites are too big, part of it will lodge in my nasal cavity (uvula too small to block anything).

I did hear about the hyperbaric therapy in the early 2000's, but at that time it was indicated to me that the marrow in my jaw was likely dead too long. However, I got that from a GP. I didn't follow up with a specialist at that time because I was just out of school and had no medical coverage.
