If you’ve never been jolted out of bed with painful muscle contractions in your legs, consider yourself lucky. This is an unfortunately common issue, particularly for women.
Q: What are leg cramps?
Marla Ahlgrimm: Leg cramps are an involuntary, sudden, and extremely intense, often painful contraction of the muscles in your upper or lower leg. Sometimes, foot cramps can also trigger cramps in the lower leg. You may hear someone refer to leg cramps as a Charlie horse. Regardless of what you call it, it is uncomfortable at best.
