Christine, I will ask my docs on my next visit re HBO, it may help to save my teeth, but I doubt it after what my GP inferred ib my last visit. I have not been able to eat properly since my surgery and this got worse are radiation and now getting worse again from the loose and aching teeth, I am only having soups and creamy stuff. Because of my teeth but mainly because I have a lot of tissue damage and find it very difficult to swallow. They want my to have my throat stretched. Another question I have is that do any of you still get days where you are sick the same as with the chemo sickness. It happens to me once or twice a month. Plust I have the cataract problem, but as you all say Radiation is the gift that just keeps on giving.
