So sorry to hear what you and your husband are going through! I wonder how he's doing by now. I've found that even though I ask questions, many times the answer is a glum stare, a shrug, or simply, this is one of the long-term effects of radiation treatment. It begins to feel like Drs. treat what they can and they they can be done--they don't have to deal with the aftermath, which is ongoing and terrible.
