I realize this doesn't answer your question but I thought I should post it.

I got rid of my lymphedema using massage. My ENT showed me how to do it. I would apply medium pressure above the lymph nodes starting right near my ear lobs, and stroke down. Not pressing hard. The idea is to encourage the lymph to drain from the lymph nodes. I got into the habit of doing this a few times a day, several strokes each time. It took several weeks, but one day I went to do it and noticed it was all gone.

The other choice I had was the cancer center where I was treated offers a lymphedema evaluation and treatment. My ENT had written me a prescription, but because it's all gone now I canceled the appointment.
