I am so glad for you that it wasnt a tumor. Thats great. Ive had a sore spot since almost the beginning of rads. it is from my tongue rubbing on my tooth. I have a cross bite. one of my molars is in a little, not normally a problem but my new tongue is still swollen from radiation so it pushes it into it! UGH! so I am having that tooth filed down in a few weeks. Maybe your sore spot could be residual irritation form radiation or even from the chemo. I did decide to try the budwig protocol.. i am practically vegan as well. though I do eat eggs ocassionally - and I dont do dairy. but once a day I do the budwig thing. There is a book called the anti cancer book I read - it talks about different foods and their affect on cancer cells it might help you to read it. Good luck with the rest of your treatments... take care! and hugs.
