I would like to add that not all of us react to radiation like Marica's husband. My skin reacted just like a common sunburn. It never got raw or weepy as some do. It peeled and then healed quickly. Today it is smooth, tanned and hairless. The radiation killed all of the hair folicles on my neck so I will never have to shave there again. It also took out some skin tags and small moles. My wife is an esthetican and extracted all of the dead folicles (it wasn't any big deal, they practically fell out).

Caution: You don't want to have any petroleum products (or anything else) on your throat DURING radiation (i.e., while you are on the table)-it can exacerbate the skin damage. Apply these products AFTER your daily treatment and on weekends.

The skin cream they gave me for itching was called "Desonide cream 0.05%", I only needed to use it a few times when the itching was too much.
Do not scratch the area!

Another thing. You will have to avoid the sun and wear SPF 30-45 sunblock for the rest of your life (which you should be doing anyway). We are at greater risk for skin cancer, having received a lifetime dose of radiation.
