Can anyone tell me what is meant by mild OA as it does not feel mild to me :???:. Also how does it stand with the blue badge scheme when you can have good periods where you don't need a stick and really bad periods where you rely on your stick as walking is too painful. As at the moment I am going through one of those bad periods with my knee and I have been given a blue badge. I know with OA you can have really good periods too, I hope mine is soon
. Basically I will not use my blue badge when im on a good period, I just wondered if you had to send them back or something, if your condition improved.
