Answering my own question for the good of others who happen upon this thread later:

Google says 6-8 weeks is how long it takes to heal after radiation. I'm more sore now than I have been in weeks and I wonder if what I'm eating or drinking is causing there backslide. Luckily I am meeting with my oncologist (rather than my useless radiation doc) on Wednesday. Hopefully he'll have more info and advice for me.

Anyone with info on their healing, I'd still love to hear from you!
