A few things can cause cramping. If you are cramping in your calf muscles you need to stop, flex your foot towards you, hold for several seconds and release (do not point your toes, it'll make a cramp worse) while massaging the area of the cramp until it subsides. Cramps most likely happen because you are dehydrated and need extra fluid. Remember that if you are exercising, you should be drinking cold water before, during and after to keep from dehydrating those muscles. They need the fluid to work. Another reason is that your potassium level is off. If you are exercising hard, a good sports drink, like Gatorade, will help relieve the cramping because it will restore your electrolytes (sodium and potassium levels) to a normal state. If cramping persists, try adding foods like bananas, yogurt or oranges (orange juice works too) to increase your potassium consumption. Sometimes a vitamin deficiency can affect your muscles too. Taking a good multivitamin should also help.
Hi, sorr. Honey, if you're talking about the kind of leg cramps that make your legs jerk during the night, there is a prescription medicine called Mirapex that will help. If you're talking about cramps like charley horses, then there are several things that can cause them. Low potassium can cause them, but other things like vascular status of the limbs and perhaps electrolyte levels could also be a cause. The best thing to do, would be to see a doctor just because of possible underlying problems.
