Leg cramps and sensations are common during pregnancy, especially in the second trimester. They can be caused by various factors such as hormonal changes, increased weight, pressure on nerves, or changes in blood circulation. To alleviate discomfort, try stretching exercises, staying hydrated, maintaining proper posture, wearing supportive footwear, and avoiding standing or sitting for long periods. If the pain becomes severe or persists for an extended period of time, consult your healthcare provider to rule out any underlying conditions.
