Causes of Muscle Cramps
Actually there are no biological explanations for muscle cramp. Most of them are harmless, but some muscle cramps are linked to certain medical conditions:
Atherosclerosis-inadequate blood supply caused by narrowed arteries may increase the risk of getting Muscle Cramps.
Nerve compression. Nerve compression in your spin can cause pain in the buttock or leg. The longer you walk, more pain you will feel. And the pain will go away as soon as you stop exercising.
Mineral deficiency-inadequate supply of potassium, calcium or magnesium can lead to muscle cramps. Some medication like diuretics can break down the mineral balance in your body and contribute to muscle cramps.
