Muscular Cramps

Painful sensation caused by the contraction of muscles is known as cramps or muscle cramps, Charlie Horses or spasms in layman’s language. Muscle cramps cause visible or palpable hardening of the involved muscle. There is nothing to worry about when if you are suffering from cramps, as around 95% people get muscle cramps at some or the other point in their life. It is extremely common in adults, and the frequency increasing with the increase in age. Although rare, children too suffer from it while playing, jumping and even sleeping.

Muscle cramps involve a part of a muscle, the entire muscle, or several muscles that usually act together. In some cases, the contraction is simultaneous in the muscles that ordinarily move body parts in opposite directions.

Types
True cramps: Most common type of skeletal muscle cramps, true cramps are caused by hyperexcitability of the nerves that stimulate the muscles. True cramps are a result of vigorous activities like sports, injury, dehydration, low potassium levels, low blood calcium & magnesium.

Contractures: Contractures occur when the muscles are not able to relax or they are fatigued. This is caused due to depletion of adenosine tryphosphate (ATP), which acts as a source of energy for the cells and helps the muscles to work.

Tetany: The type of cramping which activates all the nerve endings in the body is known as tetany. Besides affecting other nerve functions in the body, tetany affects the muscles of the body and thus results into cramps.

Dystonic cramps: These occur when the muscle, which is not needed for a movement is contracted. It usually affects the smaller muscle groups like eyelids, jaw, larynx, etc.

Abdominal cramps: Painful muscular contractions in the abdomen cause abdominal cramps. There can be various reasons behind this type- like diarrhoea, constipation, gas troubles, etc. Abdominal cramps are also common during pregnancy.

Menstrual cramps: Menstrual cramps in the stomach, back or legs are common in women during their menstrual cycle.

Hand & leg cramps: Muscular cramps in hand and legs are very common. Besides a particular disease or side-effects of a drug, weightlifting, excessive running or stretching may cause muscle cramps in these parts of the body.
