About an hour later I could finally stand up, but the pain was still excruciating and to make a long story shorter, I spent the next 3 months limping, not knowing what was wrong with my knee (which was swollen too) and then having that injury make the arthritis flare up in my TOES of all places! That made it even more difficult to walk and to go up and down the stairs. I couldn't do my daily walks, which was very disturbing after walking nearly every day for 3 1/2 years to keep my weight and blood sugar under control.
