My husband had used a compression garment that went around his neck. Lately though he has been using a cervical collar I believe it is called. For almost 2 weeks he has not had the Hulk neck in the morning so I think it is really working. It would look like something you see on someone that has had whiplash. Just to prove this was the reason for the improvement he left it off one night and when he was up during the night his swelling was starting so back on it went. I think it is working better than the first one because it applies pressure all around his neck and keep his neck straight rather than scrunching up during the night keeping the fluid moving rather than puddling up. His massage therapist was quite happy to find something that works and he may be able to discontinue the treatments.
