What are muscle cramps?

Muscle cramps are sudden, involuntary contractions or spasms in one or more of your muscles. They are very common and often occur after exercise. Some people get muscle cramps, especially leg cramps, at night. They can be painful, and they may last a few seconds to several minutes.

• Thighs
• Feet

• Area along your ribcage

What causes muscle cramps?

Causes of muscle cramps include:

• Straining or overusing a muscle. This is the most common cause.
• Compression of your nerves, from problems such as a spinal cord injury or a pinched nerve in the neck or back
