Yes, Epsom salt soaking helps with the inflammatory response which in turn will reduce scar tissue formation (scarring of soft tissue increases pain and stiffness), this will also reduce pressure upon nerves due to swelling/inflammation and increase circulation which is needed in order to heal. Your body needs proper circulation of blood flow in order to heal. You can give your body a little help by using epsom salt soaks, massage, physical therapy, rest, moist heat and even by using compression socks and or KT tape - all good measures regardless of whether or not you have CRPS.
