It's been four months since the stem cell injections. I think there is still improvements happening. I still don't have any pain on the top of my left foot or right knee. My pain in my hips has continued to be reduced. My pain in the left knee is still significantly less than it had been before. I am still leaving my name on the list for a left knee replacement. But I'm still hoping I can get another couple of years with reduced pain. I did not do well with the excerises- I rarely did them. I'm still attempting to walk as much as possible and never less than 3,000 steps a day ... aiming for 6,000 steps. My mobility has increased, but frustratedly I still have difficulty getting up from the floor. Kneeling hurts my knees. My ankles, and the soles of my feet hurt. Most of the pain in my feet can be alleviated with the use of orthotics. I haven't found a suitable send me as yet so I live in my runners and wear birkenstocks in my house at all times - NO bare fee
