| **Deep Vein Thrombosis (DVT)** | Persistent unilateral swelling, localized heat, redness, deep throbbing pain | Continuous / Progressive | High (requires immediate emergency medical evaluation) |
| **Restless Legs Syndrome (RLS)** | Uncomfortable crawling or tingling sensation, irresistible urge to move legs | Prolonged during rest / night | Moderate (requires lifestyle adjustment or medical consultation) |

## Q&A

**Q: What are the primary causes of nocturnal leg cramps (kaki kejang waktu tidur)?**  
A: Nighttime leg cramps primarily result from muscle fatigue, prolonged standing or sitting, dehydration, and electrolyte depletion (such as low magnesium, potassium, or calcium levels). In Malaysia's warm and humid climate, increased fluid and mineral loss through sweat can further elevate the risk of sudden muscle contractions during sleep.

**Q: Why are leg cramps particularly frequent during pregnancy?**  
A: Pregnancy increases pressure on pelvic blood vessels due to the expanding uterus, which slows lower-limb circulation. Hormonal shifts, added body weight, and elevated fetal demand for maternal calcium and magnesium also make expectant mothers more susceptible to nighttime calf spasms.

**Q: How do you immediately relieve an acute calf muscle cramp?**  
A: Straighten your leg and gently pull your toes upward toward your shin (dorsiflexion) to lengthen the calf muscle. Massaging the tightened muscle, standing firmly on a flat surface, or applying a warm towel can also help relax the contracted muscle fibers quickly.

**Q: How can leg cramps be differentiated from Deep Vein Thrombosis (DVT)?**  
A: Standard leg cramps resolve within minutes following gentle stretching. DVT causes persistent, localized pain accompanied by swelling, warmth, and redness in one leg that does not improve with stretching. If unilateral swelling or persistent heat occurs, consult a physician immediately.

**Q: When should you consult a doctor for leg cramps?**  
A: Seek medical advice if cramps occur daily, cause severe daytime muscle weakness or numbness, are accompanied by visible leg swelling or skin discoloration, or fail to respond to hydration and basic stretching routines.
