Elevation. Prop your legs up on an ottoman to help decrease swelling. Various
yoga poses, such as lying on the floor with your legs raised and pressed against the wall, can also help.
Epsom salt. Soak your feet and ankles for 15 to 20 minutes in a cool bath filled with Epsom salt to relieve swelling-associated pain. If you have
diabetic neuropathy in your feet, check the water with your hands first to avoid exposing your feet to extreme temperatures.
