Hi Debbie,
Wow your husband seems to be having the some of the same problems my Dad did. As far as the constipation, we tried just about everything (prescription and over-the-counter) until finding the right product. So I would keep trying.
Also, my Dad's ears were both severly burned & bloody pretty early on (2 weeks I think). (He said it felt like he was on fire!) I don't any solution other solution to that problem except using the Aquaphor. My mother and I applied it several times throughout the day. The only thing I can say, is that the ears healed pretty quickly (around 2 days) during about the 6th week of treatment.
He is also in the same boat as your husband, as far as not being able to do surgery first due to the location of the tumor(s). He has completed chemo and radiation, and is waiting to see if surgery is necessary and what type is so.
Take care!
