Last night I woke up around 1am with bad cramps in both legs and feet. I was running around the house trying to stretch them out, and started holding my right index finger to harmonize 4th Depth (kidney/ bladder – regulates balance of water in the body). In a couple of minutes, all of the cramping was gone, and I went back to sleep. Amazing! I had never actually tried this hold for leg cramps before, and I will definitely use it again if necessary!
