Hi,

I will say last year before blowing out my knee and then before TKR in January, 2021, that along with being able to walk 3 miles a day or more every day, I was able to do 25 - 30 flights of stairs at least 4 days per week. Now i if I do even 15 flights of stairs per day, my feet explode after a while especially if I sit down an relax after dinner.

Thanks, hoping you are able to figure it out.
