[|Human|] 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?
[|AI|]  HelloWelcome to Chat Doctor. Thank you for providing the brief history. What I understand by history is this is due to post surgery affect. It can definitely not be MS as there is no connected symptoms associated with this sarcoma. Regarding nerve injury I feel the location of the sarcoma should be known before giving a conclusion. As numbness can be possible if the nerve gets irritated due to any factor. Having it checked by the operating surgeon will be a good choice to look upon. Please feel free to contact me if you have any questions. Regards
