Knee pain when standing piles may be caused by the following reasons: 1. Beginners' muscles and knees are not relaxed enough, so it hurts; 2. If the knee has been injured or hidden, it will "wake up" the pain, and generally it will disappear after standing for a period of time (about two or three days to half a month); 3. Pursuing standing for a long time to improve yourself is also easy to get hurt. Do what you can according to your own physical strength, and naturally stand for a long time.

Here are some ways to relieve pain: 1. Knee pain in the process of standing piles is not pain just after getting up, but sudden pain, persistent pain or short-term pain after standing for more than ten minutes. This is a complicated factor. First of all, it must be clearly informed that the standing pile has an auxiliary repair effect on the knee joint, such as meniscus injury, synovitis and arthritis. And when this happens, you have to judge the reason.

2. When standing the pile, relax your waist first and let your knees bend naturally. Don't bend your knee intentionally, it will cause knee injury. Relax your waist, lower your hips and let your knees bend naturally.
