Walked 3/4 mile with two grandkids

We had two of our grand kids visit us for about four hours, and during that time, I walked with them about 3/4 mile. My leg felt fine during that time. Last week I had a lot of swelling in my left leg, and I took most of that week off to give my leg some rest. The swelling was gone by the weekend, and the short walk this morning hasn't brought the swelling back.
