So glad he made it home safe and the cold weather is behind him for now. I can't imagine! The swelling started a few weeks ago and he had a lot of "turkey neck" that was hanging and some days just seemed swollen. We did some research and found this is common with radiation to the head and neck. The radiation seals off or gets clogged the lymph nodes and the fluids don't know where to drain to. He starts occupational therapy today and for two weeks after. They use a series of light massage and compression with an ace type bandage to open things up and redirect the built up fluid so it drains. I will keep you posted but look for swelling in the neck, throat, back of neck and chest wall. The OT said if caught early that it's common and not a problem.
