Budgie - welcome to our family. We're here to help. Also congrats on getting through a tough treatment. You fit the profile of many of us in the weight loss department!

I'm not sure about the blisters. I had tons, but they eventually went away. In my case I started on liquid nutrition maybe 2 weeks into radiation and wasn't ready for solid food until a good 6 months after. So that fact that you're eating solids 4 weeks post rads is amazing to me! I trust you're keeping it to the soft and wet stuff.

Anyway, I'm sure someone will weigh in with a comment that more specifically speaks to your concern. Hang in there!
