When I got up this morning the swelling in my feet was a bit worse than it was last night. Also, I had hot spots on the bottom of both feet from, I think the covers being tucked in at the bottom of the bed and thus pulling tight on my toes contributed to the swelling. In the hospital the covers weren't tucked in. I went up the stairs last night and again a few minutes ago, and that is a good sign. All in all, I'm doing fine today. No running, of course. Just walking around the house.
Later: I'm on my way to bed and thought I'd report on my condition. I've been up and down the stairs several times today and have had no problems. I noticed a slight increase in my breathing rate, but it went back to "normal" within a few seconds. I'm able to stand longer and walk longer distances, but my feet are still swollen. Today has been a good day for me.
