Home cures for muscle spasms include taking a hot shower, placing a cold compress on the affected area, and drinking plenty of fluids, according to Native Remedies. Consuming more potassium, magnesium and calcium may also help ease the cramping.
Muscle spasms often occur in the legs, knees, neck, shoulders and abdomen. Causes for muscle spasms include stress, poor circulation, acid reflux, childbirth and nerve injury, notes Native Remedies. Children experiencing a growth spurt may suffer more from muscle cramping, as their bones become too long for the tense muscles in their bodies. These spasms last approximately one to 15 minutes.
