Calf muscle soreness after climbing is often caused by lactic acid accumulation, which can be relieved through bath, massage, hot compresses and medication. Bath, massage, hot compresses and other methods can promote blood circulation to reduce the accumulation of lactic acid, thereby reducing pain; at the same time, appropriate stretching can also promote the reduction of calf pain. In addition, low-intensity aerobic exercise can also promote local blood circulation to reduce pain. Muscle pain after climbing is common within 24 hours to 72 hours after climbing, mostly due to the accumulation of lactic acid caused by excessive climbing intensity, long-term lack of exercise or incorrect climbing posture. Therefore, you should pay attention to exercise, and reasonable arrangement of climbing intensity, fully warmed up before climbing, and appropriate stretching exercise after climbing to reduce the accumulation of lactic acid. For more serious calf muscle soreness after climbing, you can consider taking oral non-steroidal anti-inflammatory drugs such as Loxoprofen sodium and Celecoxib for treatment. If the pain is more intense or difficult to relieve, it is recommended to seek medical attention as soon as possible and follow your physician’s recommendations for treatment.
