I've just started radiation - today was my second treatment. This afternoon, a few hours after the treatment, I started noticing a very uncomfortable "puckering" feeling in my left cheek - enough to make me moan out loud and grab my face. It comes and goes. It feels like I'm getting ready to suck on Sour Patch kids and my body is anticipating it - only I'm not and the discomfort is way worse than when eating sour candy. Also - suddenly my neck incision is painful and tender again...

I'm not a happy camper as I expected that the discomfort/pain from radiation wouldn't start until the 3rd week. Has anyone else had these issues? Any advice for dealing with it?
