Michael,
My husband used lollipops that deadened the pain. He claims that he would not have made it through his radiation without them. They are made by a particular compounding pharmacy in Gainesville, FL. The active ingredient is Tetracaine. They are by prescription, only. This particular pharmacy makes them for the Head Cancer Center in Gainesville - I'm not sure what the rules are regarding posting their name and phone number on the Forum site. If anyone would like their contact information, I'd be happy to email it.
