No - I don't think so - that would make the situation worse (the rads I mean) you've got an infection , and burning and a rash (open sores?) you need to give your neck time to heal a bit. Take the antibiotics, keep the area clean - I am assuming they are continuing the rads just giving you a break from the Erbitux? It's okay to miss a chemo - some of us do. I missed a bag. Plus with Erbitux since it works differently than standard chemo I believe they can make up the dose post treatment. The only reason I could see them giving you more rads would be if there is still cancer present. If you miss a rad treatment they should of course make it up. Hugs and keep on trucking.
