Hi there.
I am 12 weeks post tx for cancer to the tongue, and I am still in a lot of pain, and still on the peg tube. It is too painful to swallow for me still. I seem to have an infection which is being treated, so hopefully when that clears up so will some of the pain. I had been doing well, gradually noticing improvement each week, but now it seems like a setback.
I think it is just a really long, long process for healing, and for some of us it just takes longer. I would check out the possibility of a bacterial or yeast infection, which are painful as well.
