Hello - my husband John had a lot of swelling around his jaw and into his neck area after completing chemoradiation in December. He didn't have any surgery. It was ( and still is) worse in the morning after sleeping all night.

The radiation oncologist dismissed it as "radiation dewlap" - the build up of fluid that others have talked about due to disruptions in lymphatic fluid flows. Lately, it has taken on a more woody texture but the doctors keep assuring us that these changes are normal for many people.

John has no pain associated with the swelling though and that is a big difference from your brother's situation.

Mary
