Garvin: Welcome. I recently had radiation on my lip and since a shield was placed inside the lip, my mouth was not involved. Therefore, I can't tell you much about when you can eat but I can tell you that for six weeks after treatment I experienced pain and discomfort. After that things got better so I will guess that you may be able to anticipate the same sort of ball park. My radiation ended in January and while reminders of it exist, they are tolerable.
