I know it sounds strange, but for a while now and it's getting worse, when sitting on chair with feet on floor, my knees are tight together, and the harder I try to push them apart the tighter they get. Even my wife has tried pulling them but no joy. Then one leg starts jumping like twitching and it kicks the other leg. I try squeezing a bucket between my knees to separate. Does give after a while. But goes back again is it the MS? Or a back problem? Going to see back specialist but not till October. Good old NHS. Anyone the same? Can't really walk now even with walker one foot goes behind the other. Then I'm stuck. Anyone?? Thanks.
