The longer version: My left foot, where the burr was is totally fine. I think 65MD's 'surgery' on it is what made it so sore the next day. I also think the burr came out even though he didn't think so. After that one day of concern, it never bothered me again.
My right foot, where I snagged my pinky toe on the wooden pallet is much better. It does not hurt to walk. It hurts sometimes when it is touched just the right way. I mostly wear open toed shoes so it isn't a problem. Once I get my walking shoes on, it is fine there too.
My feet are fine for walking. My hips are too. They are just a little more particular about the surface. They aren't too wild about concrete and uneven surfaces. They're getting better at those and even better at the stairs. Stamina, building up endurance is the name of the game for me now.
I'm on my way. I wound up with an average of just over 5800 steps per day for the last 15 days. It is down slightly from the first challenge, but that one was shorter and I had a little more control over my days (no family trip). I expect to reach my 6000 average goal this time and sport some new clothes by the end of the month!!
