For immediate relief from a foot cramp, gently stretch and massage the muscle, or apply a warm compress. To prevent future cramps, ensure you stay well-hydrated. You may consider an over-the-counter magnesium supplement, as magnesium deficiency is a common cause of muscle cramps. While pain relievers like ibuprofen can help with residual soreness, they do not prevent cramps. Please consult a doctor if the cramps are frequent, severe, or accompanied by swelling, redness, or muscle weakness, to rule out underlying circulation or nerve issues.
