Simple hydrotherapy for sore and slightly swollen feet. It’s called Wet Sock/Dry Sock and it’s done just before a person goes to bed. A person needs a pair of mid-calf cotton socks to allow air to go through easily. Take one sock and run it under cold water then wring it out. Put the wet sock on the affected foot then take the dry sock and put it directly over the wet sock. Have the foot stick out of the bed sheets to allow for better circulation. The wet sock will tell the body to send more blood flow to that area to warm it up. This will increase the circulation into the foot. By morning both socks will be dry as well as the soreness and swelling will be decreased. This hydrotherapy should be repeated nightly to have a positive effect.
