Carol,
Just to add to the prior posts above. The Lymph node system has roughly 100 or so Lymph nodes just in the face and neck area. Once I found out what the problem was, I was directed to a Cancer Physical Therapist. I was taught a very simple massage that will stimulate the flow of the Lymph node fluids. The over worked Lymphnodes fill up and cause the swelling and tightness in the neck.
I had roughly 30 lymph nodes removed in my neck dissection/ resection ( right side ) . The swelling can cause the throat passage to narrow and cause problems swallowing as stated above. Also the after effects of Radiation. Once the massage is learned, a person can do it several times a day and it should help out from anywhere between 4-6 hours and may have to be repeated again.
As I was told, gravity is our friend in this case as the fluids do want to drain towards our stomach area. The Lymph node system moves at 1/3 the speed of our blood flow. Those with leg Lymphodema have a much rougher time than we do, from what I was told by the Therapist.
Alot depends on the persons activity each day. Bending over and having your head in a low position causes swelling as well as lifting heavy items. I'm sure your husband is uncomfortable when sleeping in the incline position, but it might help him for now if he can maintian that position for awhile longer, until his body adjusts. My swelling isn't as bad as it was 2 yrs ago. But it still happens.
My Best to Everyone here
