Thanks so much Christine for your response and input. It is always SO encouraging to me when someone familiar with OC tells me there's still time for my saliva production to improve. My surgeon told me that wherever I am a year post rads is pretty much where I'll be in my recovery, and being a month and 1/2 away from that target is very depressing, to say the least. My radiation doctor is the one who mentioned HBO and told me about the positive results they have seen in salivary gland repair. He prescribed the pilocarpine to me a month after rads and it had no effect on me. No increased saliva or sweat. Do you recall your saliva improving at all after all of your dives, or did you already have your saliva back? I know I'll never get all of my saliva back, but I would love to have enough back to allow me to chew food up enough to be able to swallow it. Ya know what I mean? Do you eat solid food? Like a sandwich? Thanks again for all of your encouragement and experience sharing.
