Hi,I am recovering from surgery so my typing is bad.We have e-mailed before, I had the same operation as you mom but mine failed. The flap may be infection rather than cancer, blood and pus was what I had in my last infection, and they biopsyied regularly because I thought the same thing. No cancer. I had several surgeries after failure, so it is hard to relate recovery to your Moms but I was allowed to eat after 5months, get her to try putting food at the roof of mouth and softening, then swallow, with a little work she can keep most food away from front of mouth.The leg I walked on early and was doing a mile a day or more on by 5 months, I am a lot younger than your Mom and have always had strong legs. My leg changes color once in a awhile and will get painful if i set too long or not exercise it regularly. I do not think leg problem related to jaw problem. I am not a Doctor, and yours should of had someone cover your MOMs case while he was away , if for nothing else for peace of mind thatyou had one to question. I would be angry also.You said once you mom had poor circulation, this could cause some of color changes in leg. Keep us updated. gnelson
