@harleytiger I am happy to hear you are done being zapped. Many of us had 35 rounds or seven weeks of radiation. Those last two weeks did the most damage to me and I'm sure others would agree. It's like making toast and then watching it burn instead of popping it out.
The thick saliva will likely hang around for a few months as you heal. Lovely I know, right?
Your nose runs, common thing for many of us. Some say it is a salivary gland re-route. I have a friend who leaks saliva from a small fold in the neck when she eats since radiation. I have the runny nose while eating all these years out of radiation.
Your neck will be stiff. You likely will have brief nerve pains in the neck, shoulders and arms. Be careful eating dry foods, breads, rice, white meats. Lack of saliva. Most issues go away in a few months while others might hang around for years or forever. The good thing is you are on the mend. You got through what very much the thought would scare most people.
Good healing and welcome to life post-cancer.
