Hello Barney

Welcome to the Oral Cancer Foundation Forum. Click on the faq at the top of the page, it will help you learn about this website.

There are two search engines here. One at the top and one at the bottom of each page. I have not had any of your symptoms as I am just starting my treatment. I am supprised that not that many people answered your questions yet?

Click on "search" at the bottom of this page and type in "trismus". Do the same at the top search.
I believe most of your problems can be helped by stretching exercises. Your mouth problem seems like trismus. (lock jaw) Read the search results and try the suggested exercises.

It would help if you added your Tx & Dx in your signature box. In the "General Board" forum there is a topic titled "how to get the most out of this forum". This will also help you a lot.

Is your PEG tube permanent? There is so much we do not know about you to help answer your questions.

To me, not being able to open your mouth (trismus) is the most serious of your symptoms. I feel it would be best for you to make an appointment at your VA Hospital and go over all these problems and get a doctors advice, and have the Dr. prescribe some physical therapy. Read and try the information you will find in your search answers.
Please report back. Open a new topic in the "After Treatment Issues" forum. Tell us about your "journey" and ask any questions you like. Looking forward to chatting with you in the future. Good Luck, Petey
