OK my dear,
Take a deep breath and calm down a little if you can. I too have been struggling with lymphedema in my face and my left jaw was pretty swollen for awhile. What I did was found a lymphatic therapist and she did wonders. Its just a matter of getting the fluid to learn a different path in order to drain. I also have a mask I can wear at night to keep the fluid from building up in my face. I know its scary to see her like that but once the fluid learns a new way to drain you will see a dramatic improvement. You will see an improvement also after just a few visits to the therapist.
Everything will be fine dear, this is just a minor setback. Feel free to PM me or email me if you have any questions. Ask your doctors about a therapist there at the hospital which is where mine was.
Billy
