Use a little ice. To calm down the muscle spasms, use an ice pack or cool compress on the area youâre experiencing the charley horse. Never apply ice directly, but wrap it in a towel or bandage before placing it on your skin. Do this for 5-15 minutes for the best results.
Nighttime charley horses could also stem from peripheral artery disease, which causes the narrowing and hardening of arteries that supply blood to the legs and feet. But, as Kirschner points out, that condition should also produce cramps while walking.
