I wake up every morning with my right ankle basically frozen solid. I’ve been working on fixing my ankle range of motion for almost 18 months now and am just FINALLY starting to make some progress. In my case there are a whole lot of tissues stuck together that aren’t supposed to be stuck together. After working at it for months I’m finally able to get enough movement to get the connecting tissues to separate. You have to keep testing your range of motion and working through the restrictions. Repeat. My physical therapist says I should have enough dorsiflexion in my ankle to get my knee about 4 inches past my toes. It takes about 50 pistol squats (holding on to something) before I’m able to achieve that kind of range of motion. The range of motion doesn’t stick for long, but it gets slightly easier every day. Just got to keep working at it.
