Cancer4,
I had lymphedema since my surgery (Aug.2002), it was in my left face above and below the jaw bone. 6 weeks after the surgery, I had my first infection in my chin which forced me to halt radiation and be hopitalized to drain the pus. One month later, another infection occurred and 6cc pus was drainged by syringe. Another month later, it was infected again. It was be very painful when there was infection, and the tissue in the area became so tight that the jaw would be locked. so, maybe you need to rule out any infection.
Since I had mandbulotomy and the location of infection was so close to the titanium plate that holds my jaw bone, the doctor was very concerned that I may get osteomylitis. So, I was sent to have hyperbaric oxygen treatment.
At this moment, the swell in the face has reduced a lot but it is still noticeble and it would come and go, I always got puffy face after meal because of the chewing (I guess).
I will start the massage suggested by Joanna and see what will happen.
