I am back in Iowa from AZ now, and have continued my walking each day. Now here in Iowa the humidity is about 60%, in AZ about 4% when I was there for 6-7 weeks. My whole body is a river of sweat. My pants look like I walked out of a pool. My feet have become swollen since I am back home and my second toe under the toenail has turned a bright redish-purple and is very painful..along with the burning on my top 3 toes on my right foot..I wear crocs when I am not on the walking path and it seems to help a bit...the dry heat even though 112F is much better than 85F with 60% humidity..everyone have a safe holiday!
