I was dx w/ a parosteal osteosarcoma last Dec. In Jan my doctor performed a wide section reconstruction of the left femur. Not 7 months post op, I noticed a small area on the lower part of that leg is numb. Is it related? Could it be nerve damage? Or could in be something so unrelated like MS?

Summarized question: What causes numbness in leg when suffering from parosteal osteosarcoma?
