question... for the first time I have swollen ankles... what to do??? some say to just prop up and stay off of them... I want to soak them in hot water and Epsom salt.. seems it will make them feel good.. but does it make swelling better or worse? also... I used all my Epsom salt last week and don't want to go back out... what do u girls use to soak feet in other than Epsom salt that works? thanks
