Well, we went to the specialist today. They xrayed her lungs and they are all clear but when they did those xrays they caught a bit of her shoulder and they said there was "something" going on there so they did xrays of her shoulder as well. They are going to go over them and call us on Thursday as we had been there for hours, they were essentially closed and they still had a mother load of people to deal with. Basically, if we decided to go with amputation and chemo, that would be her remaining leg.
She said although she couldn't feel anything with her hands, the cancer could have spread there or even started there. Strangely enough, when she started getting limpy that is where I thought she was sore until the swelling on her leg showed up.
