Maybe someone else can add to this or u can ask at radiation tommorow. I remember toward the end of radiation my mom was complaining of the same thing. I do remember she was using some sort of cream, Aquafor i Think she had some sort of blue gel pads that were refrigerated and then placed on her neck. That she could hardly stand because it was too cold. But she used washclothes instead and laid on the couch and napped with them on. The rad nurses reccomened this, but i cant remember why. maybe someone else has some good ideas.
