Why is only one side/hip (left) numb after lipo? 11 days post surgery (Photos)

11 days ago I had ultrasonic assisted lipo, a TT and BA. Everything is going great & healing well. Today I randomly noticed that I am numb on my left hip/side. Normal, I know. But there is no numbness at all on the right side anywhere- hip or side. I didn't need much lipo & really only had a bit done on both sides to help prevent dog ears. Why am I only numb on one side and feel no pain or numbness on the other side at all? He didn't forget to do it on that side did he? Can u tell by pics?
