I work in a spice mill, and I wear long pants with calf-high socks while I am working. Now that it is getting hotter, when I take my socks off at the end of the day, after sweating all day, both of my legs where the socks were, are very red and blotchy. They stay that way for a few hours to sometimes until the next day. Am I allergic to my own sweat? This is something which never used to happen. Is there anything I can do? maybe corn startch?
