I believe the hole is where the cancer used to be or close to it. I hate seeing him in so much pain when everything else has healed. The throat has healed and was a fungal infection, but now he is losing weight again because it's painful to eat again. Wondering if they can't just pop a stitch or two into it to close it up? The doctor (oncologist) looked at the hole and prescribed the paste, the radiologist looked at it and prescribed pain pills, I am thinking the original ENT plastic surgeon might have an answer? There has got to be a way to plug an open hole to keep food out that might cause recurring infection? Getting frustrated, but still thankful for the end of the worst and just dealing with the fallout.
