I started walking more last week. Did 3 miles on Tuesday, then 6 miles on Wednesday and 2 miles on Friday. Got a blister from the 6-miler. Went out and got double-layered socks and a 2nd skin dressing kit for blisters. Was going to walk again today but my back was bothering me. Will see how it goes on Monday. I can't wait to go to physio again on Friday. Too bad my regular physiotherapist is on vacation for another few weeks. She's been my best one so far.
