Yes. I sometimes feel like the weight of my entire body is being carried below my knees. I also experience balance problems and exhaustion when that happens

I describe it as two toddlers hanging onto my legs as I walk

I often feel very unsteady.

I do when I walk for more then half an hour then I start dragging my legs and rock from side to side to try to get a rythem going to make walking easer

Yes that is exactly right.
