The swelling under my neck took almost 10 months to go away completely, but I NEVER had any swallowing problems that were not related to my throat being raw inside. I'd like to know that what he is experiencing is like mine, lymphedema, and not something else. It might be a good idea to just be sure that there is no infectious process going on here, to have someone in the know take a look/see. A visit to the surgeon ahead of schedule might be in order to eliminate anything bad and to put your minds at ease. Lymphedema takes a long time to resolve, and my "waddle" is still there 5 years later. Tell him not to be such a tough it out kinda guy, and get his butt over to the doc for a look. Tell him it's for your peace of mind not his.....
