Possible causes of calf muscle pain after physical education class may include the following: 1. Lactic acid buildup: Sudden intense exercise or insufficient regular physical activity can lead to accumulation of lactic acid in the muscles, which cannot be metabolized in time, thus causing muscle soreness. This pain may become more noticeable at night. 2. Muscle strain: Inadequate warm-up before exercise, excessive range of motion, or incorrect posture during exercise may cause calf muscle strain, leading to local tissue congestion and edema, and resulting in pain. Severe strains may cause muscle bleeding, and prompt medical attention is required. 3. Other causes: There may also be other reasons such as pre-existing calf conditions or lumbar spine diseases, such as lumbar spinal stenosis or lumbar disc herniation, although these situations are relatively rare. It is recommended to rest appropriately, apply heat compresses, and perform massage to relieve the pain, and seek timely medical attention when necessary.
