I am a 21 year old female. On January of '09 it was discovered that the lump on my neck was a mucoepidermoid carcinoma. I had two surgeries and radiation on the area. Now, almost a year after my radiation ended, my neck muscles are in constant spasm on the side where all the work was done, particularly right in the front. It causes a lot of pain. My doctor is searching for a cause, and more specifically, a solution, but he hasn't seen anything as extreme as mine before.
