Welcome, but sorry for your treatments, and surgery. Other than it taking time, maybe ask your doctor about a therapist that specializes in lymph drainage therapy, LDT, and doing light exercise like walking, swinging arms to get the Lymph fluid flowing, and when that can be done after surgery. The manual Lymph drainage has to be done a certain way...direction, pressure, and each area in the face, neck has a different pathway to do, so it's best to see a professional. Some find Lymphdemia relief with acupuncture also, but again, see when, and if that can be done. Good luck.
