Muscle Cramps
Mild
Muscle cramps are sudden, involuntary contractions in one or more muscles that do not relax immediately. They commonly affect the calves, thighs, feet, hands, arms, or abdomen and may occur during exercise or at night. A cramp can be painful and may last from a few seconds to several minutes. Most cramps are temporary, but frequent or severe episodes may require evaluation for an underlying cause.

When to Seek Medical Attention
Most muscle cramps are mild and are not emergencies. Seek medical assessment when cramps are frequent, severe, persistent, or associated with weakness, swelling, or other unexplained symptoms. Prompt evaluation is appropriate for severe generalized cramps, fainting, significant weakness, or symptoms occurring with serious illness or dehydration.

Overview
Muscle cramps are sudden, involuntary contractions in one or more muscles that do not relax immediately. They commonly affect the calves, thighs, feet, hands, arms, or abdomen and may occur during exercise or at night. A cramp can be painful and may last from a few seconds to several minutes. Most cramps are temporary, but frequent or severe episodes may require evaluation for an underlying cause.
Symptoms 2
Leg Pain
Muscle Weakness
Causes 1
Muscle cramps can result from muscle strain or overuse, dehydration, or low levels of electrolytes such as potassium, calcium, or magnesium. Other possible causes include nerve compression, reduced blood flow to muscles, pregnancy, certain medicines, dialysis, thyroid disorders, and other medical conditions. Cramps may also occur without an identifiable cause. During exercise, inadequate fluid replacement and excessive muscle use can contribute.
Sedentary Lifestyle
Risk Factors
Cramps are more common in older adults, athletes, people who are overweight, pregnant people, and individuals with certain thyroid, nerve, kidney, or circulation disorders. Prolonged or strenuous exercise, exercising in hot conditions, dehydration, and medicines that affect fluid or electrolyte balance can also increase risk. Individual risk depends on activity level, health conditions, and medications.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Most occasional muscle cramps can be identified from their typical symptoms and do not require extensive testing. A healthcare professional may ask about exercise, hydration, medicines, medical conditions, and the timing and frequency of cramps. If cramps are severe, recurrent, prolonged, or accompanied by weakness, swelling, redness, or other symptoms, examination and blood or other tests may be used to identify an underlying problem.
Prevention
Key Prevention Tips
Regular stretching, gradual increases in exercise, adequate fluid intake, and appropriate recovery can help reduce muscle cramps
Stretching before exercise and before bed may be useful for people who experience recurrent leg cramps
During prolonged or intense exercise, replacing fluids and electrolytes may be appropriate
Persistent or severe cramps should be assessed rather than relying on supplements or medicines without medical guidance
