In daily life, there are many causes of knee pain and swelling, such as prolonged standing, sitting or squatting, resulting in increased weight-bearing in the knee joint, or prolonged exposure to cold in the knee joint, resulting in poor local qi and blood flow, stagnation of qi and blood stasis, and obstruction of meridians, which can produce pain and swelling in the knee joint and affect activities. In addition, patients with osteoarthritis or osteoporosis in the knee joint may have clinical symptoms such as soreness, tenderness, weakness, and popping or increased pain during activities. After the above clinical manifestations appear, the patient needs to be seen in a timely manner to make a clear diagnosis and take the correct treatment, which can alleviate the uncomfortable knee phenomenon.
