Muscle cramps
Cramps - muscleMuscle cramps are when a muscle gets tight (contracts) without you trying to tighten it, and it does not relax. Cramps may involve all or part of one or more muscles.
The most commonly involved muscle groups are:
- Back of the lower leg (calf)
- Back of the thigh (hamstrings)
- Front of the thigh (quadriceps)
Cramps in the feet, hands, arms, abdomen, and along the rib cage are also very common.
Muscle cramps are common and may be stopped by stretching the muscle. The cramping muscle may feel hard or bulging.
Considerations
Muscle cramps are different than muscle twitches, which are covered in a separate article.
Muscle twitches
Muscle twitches are fine movements of a small area of muscle.
Causes
Muscle cramps are common and often occur when a muscle is overused or injured. Working out when you have not had enough fluids (dehydration) or when you have low levels of minerals such as sodium, potassium, or calcium can also make you more likely to have a muscle spasm.
Muscle cramps can occur while you play tennis or golf, bowl, swim, or do any other exercise.
They can also be triggered by:

Home Care
If you have a muscle cramp, stop your activity and try stretching and massaging the muscle.
Heat will relax the muscle when the spasm begins, but ice may be helpful when the pain has improved.
If the muscle is still sore, nonsteroidal anti-inflammatory medicines can help with pain. If the muscle cramps are severe, your health care provider can prescribe other medicines.
The most common cause of muscle cramps during sports activity is not getting enough fluids. Often, drinking water will ease the cramping. However, water alone does not always help. Salt tablets or sports drinks, which also replenish lost minerals, can be helpful.
Other tips for relieving muscle cramps:
- Change your workouts so that you are exercising within your ability.
- Drink plenty of fluids while exercising and increase your potassium intake (orange juice and bananas are great sources of potassium).
- Stretch to improve flexibility.
When to Contact a Medical Professional

- Are severe
- Do not go away with simple stretching

Groin stretch - illustration
Stand with your legs wide apart. Shift your weight to one side, bending your knee somewhat. Do not let your knee bend beyond your ankle; in other words, you should be able to look down and still see your toes. You should feel the stretch in your opposite leg, which remains extended. Both of your feet stay flat on the ground facing forward. Hold for 10 to 20 seconds, then lean to the other side.

Hamstring stretch - illustration
Extend one leg in front of you with the foot flexed. Bend your other knee and lean back slightly. Your pelvis should be tilted forward. Keep your upper body upright as you hold the stretch for 10 to 20 seconds, then switch sides. You should feel the stretch up the back of your extended leg (all the way up your calf and thigh). NOTE. Your supporting leg may get tired, as you have to balance your weight on it.

Hold on to something for balance. Standing on one leg, grasp the foot of the other leg. Keep your knee pointing down. Pull up with light pressure. You do NOT need to pull up all the way to your buttocks. If it feels uncomfortable or painful, you are putting too much strain on the knee joint. Hold your foot behind you for 10 to 20 seconds, then switch sides. You should feel the stretch in the front of the thigh.
