Leg cramps are often painful and involuntary The Back Pain Breakthrough Review  contractions of the muscles of the leg. Yes cramps occur in all muscles and the results range from annoying to excruiating but leg cramps, especially those at night, are in a class of their own. Leg cramps are also called "charley horse" in common parlance. The leg muscles usually affected by cramps are the ones that cross more than 1 joint. E.g.- the quadriceps muscles of the front of the thigh cross two joints- the hip and the knee. The hamstrings muscles behind the thigh also cross the hip and knee joints.

Much work has been done by medical researchers in this field. Among the many causes found to trigger these contractions of muscles are changes in electrolyte balance in the blood. The commonest examples of this phenomenon are hypokalaemia or low blood potassium levels and hypocalcemia low blood calcium levels. Imbalances in these electrolytes cause muscle cells to swell due to resultant osmotic changes. The other factors which encourage cramps are muscle fatigue and excessive physical exercise. Both of these factors possibly cause localized electrolyte/ lactic acid changes. Other contributory factors are obesity resulting in increased weight bearing by the leg muscles, and certain medications. Cramps are also known to occur during pregnancy, especially when the other factors provoke cramps and in dehydration.

Experts and physicians, who have studied this phenomenon, recommend proper hydration or sufficient intake of water during the day and especially during exercise or vigorous physical activity. It is also advisable to relax or take breaks during exercise to prevent lactic acid build-up in the leg muscles. Stretching of muscles after exercise is also advised. Sports advisors also suggest gradual increase in physical activity, rather than sudden spurts of exercise to prevent cramping. For example, a person who usually goes on short walks should not attempt a marathon or long jogs. The patient of cramps should also have frequent blood tests to assess the blood electrolyte levels, notably potassium and calcium.

Conservative treatment of cramps includes gentle massage of the affected muscles and warm baths. Both of these are usually sufficient to control muscle spasms. If this does not work, the patient must consult a doctor. Blood tests must be done to rule out electrolyte level changes. Among the main medicines used for leg cramps are B complex-vitamins, naftidrofuryl and calcium controlling medicines. Quinine is also believed to be useful in this condition.Foot pain is one of the most common problems that is being experienced by people all over the world. These bones will combine together in such a way that they will be putting an extreme amount of reassure on the entire foot. Muscles are also another important part that will provide a good structural resistance for foot. This is why is important to dedicate time to building your muscles and becoming stronger.
