I have a question. As I said before, I am 3 months out and doing well. But in the last week or so I have had slight numbness and stiffness in both knees. No pain, just stiffness and numb. I am doing everything I should be doing and it's still hanging in there. It appears to be normal in the process. Has anyone else had this happen at the 3 month mark? And what did you do about it?
