muscle cramp


Skeletal muscle cramps

Skeletal muscles can be voluntarily controlled. Among skeletal muscles, those which cramp the most often are the calves, thighs, and arches of the foot. These cramps are seemingly associated with strenuous activity and can be intensely painful, although it is possible for a skeletal cramp to occur while relaxing. Around 40% of people experiencing skeletal cramps are likely to endure extreme muscle pain and may be unable to move or walk on the leg that the cramp has affected. It may take up to 7 days for the leg to return its previous, pain-free state.

Treatment

[edit]Conservative

Muscle cramps due to fatigue can be treated by stretching and massage.[13] With exertional heat cramps due to electrolyte abnormalities (primarily sodium loss and not calcium, magnesium, and potassium ) appropriate fluids and sufficient salt improves symptoms.[13]

[edit]Medication

Vitamin B complex, naftidrofuryl, and calcium channel blockers may be effective for muscle cramps. Quinine is likely effective for this indication however due to side effects its use should only be considered if other treatments have failed and in light of these concerns.[14]
