B,
I'm not sure if this had been mentioned before or not, so I will bring it up as a question. Have you talked to anyone about Lymphadema, swelling of the face and neck areas ?
I know after I had my neck dissection on the right side and 1/3 of my tongue removed, 30 treatments of Radaition. The Doctors were concerned on how my healing was going more than the swelling. It was several months afterwards that I really complained about the stiffness and soreness of my face and neck that the Radiation Oncologist sent me to the Cancer Physical Therapist.
She taught me how to get the Lymphnode system flowing and that helped with the swelling which was causing my neck to be tight and my throat to actually be smaller on the inside. So, swallowing was difficult for me. Once the swelling went down, I was able to eat better. Still no saliva, but it is better.
My Best to You and Everyone Here
