My husband occasionally gets leg cramps in the middle of the night from over exertion. One night after spending the entire day doing a ton of yard work and cleaning the garage, his leg was cramping so hard he started yelling from upstairs for me to come. His hamstring was totally locked up! I massaged his leg with Mighty Natural Relief and used the Theragun on it. I expected him to wake up a few times that night with cramping, but he slept through the night. I believe the Mighty Natural Relief was the reason he slept cramp free that night. Now when he has a day of over exertion he tries to remember to apply the Mighty Relief before bed. If he forgets and wakes up cramping he yells . . . “Get Nancy’s Rub!!!” Teresa – Youngsville, NC
