Despite having a feeding tube installed and using it regularly, my husband lost almost 30 pounds during treatment and one month after. He, too, lives on ensure, to this day! He has some kind of sores in his mouth that make eating solid food painful! So.. Yes, watch the weight! The better supplements you can take, the better you will feel throughout the treatment.

Tom also had some minor burning on the neck. We used Aquaphor twice a day and a specialty lotion we found at Sunflowers with no alcohol and aloe/shea additives. I also rubbed lotion on his face as it tended to be dry and peeling also. Toward the end, we started using Silverdene, as well. That stuff was a God-send!! It cleared up the burns in less than a week!

Best of luck to you!!

Mrs V---Ask the doc for a magic mouthwash prescription. Its made several different ways, mine was lidocain, malox and benedryl. Your husband would swish it around in his mouth for about 15 c=seconds then spit it out. It should numb his mouth long enough for him to eat. Also he should be rinsing several times per day with 16 oz warm water, 2 tsp baking soda and 2 tsp salt. If it burns then decrease or omit the salt. But the salt in it really helps! This mouth rinse will help heal the mouth sores.

Sorry Nona to go off topic. This info can help you too as you go thru treatments.

IMO, The best way to take care of your neck during radiation is NOT to have concurrent Erbitux chemotherapy. And you are doing that. (aside: this is not some personal foible, there are serious questions about Erbitux not working on 33% or more of patients and just increasing the radiation dermatitis- Dr. Gillison is checking this out as well as my CCC - although I know it to be true for me)
My RO swore by Burt's Bee Balm for his patients. My wife cannot stand the smell of it now as it reminds her of our worst times.
Whatever you use, monitor your skin. there is also a prescription gel I used: Saf Gel, a "hydrating deremal wound dressing with aglinate" although I see from Dr. Google that is now availble on Amazon (use the OCF link) and Walmart without a prescription. It was quite good and soothing.

Can you get Solugel in the States? You need to keep the burns on your neck moist, covered & and clean.....do your Cancer hospitals or centres not supply you with assistance & mouth washes?
