My PT clinic has the same mini staircase yours does. I haven’t practiced stepping down on that yet. I just started stepping down from the 3 inch wooden box this past Wednesday. I’m not sure how I’d practice this at home as I don’t have one of the wooden boxes. Once I get better at it, I’ll practice on my own stairs.
My right leg is not recovering as quickly as my left leg. I’ve been dealing with pain behind the right knee that radiates down to the calf, around to the shin and down to the foot. It’s been causing my lower leg to knot and cramp up. I had to take muscle relaxers during the first 2 weeks after surgery. At about week 4, my therapist figured out that the pain was being caused by a super tight hamstring in my right leg. He gave me a bunch of stretches and exercises to address it. I’ve been doing them faithfully, and it’s finally getting better. It’s not 100% gone, but it’s getting there.
I hope the same thing happens with your hip pain - that it finally starts getting better.
