I'm sorry that you have had problems following radiation for your parotid gland tumor. I originally looked on this site to get information about pain following radiation for breast cancer, but when I saw your posting, I had to write. I'm scheduled to have surgery May 23 for a parotid gland tumor, and I am worried about the pain that will follow. There is a site that has a forum that specifically is devoted to those with parotid gland tumors. Do a google search on parotid gland tumors, and you should be able to link somewhere in the first few listings to the wonderfully supportive group of people who have been through this. I'm excited to be a part of both of these forums (Cancer Compass and the other one), as I really need to gain insight from people who have gone through the types of cancer related issues that I'm dealing with. Best of luck and God bless.
