The feeling of wind in the knee is usually related to cold environment, herniated disc and knee arthritis. 1. Cold environment: If you are in a cold and windy environment for a long period of time, coupled with wearing thin pants, the wind blowing your knees with cold air will produce the feeling of wind drilling into your knees. 2. Herniated lumbar intervertebral discs: when the herniated lumbar intervertebral discs compress the nerves innervating the sensation of the lower limbs, such as the distribution of the nerves in the knee, the nerve function is abnormal, which can lead to the abnormal feeling of wind drilling into the knee. 3. Knee osteoarthritis: If knee osteoarthritis is caused by trauma, degeneration or infection, the inflammatory factor will stimulate the nerves of the knee joint, thus causing the feeling of wind drilling into the knee. If you have a feeling of wind drilling into your knee, combined with pain and other discomforts, you need to consult a doctor in a timely manner, and a professional doctor to clarify the cause of the disease, and then formulate an individualized diagnosis and treatment plan.
