The invasion of external pathogens into the meridians leads to the obstruction of qi and blood, causing symptoms such as soreness, pain, numbness, heaviness, and limited flexion and extension in joints and limbs, known as Bi disease. It may include wind-dampness heat, wind-dampness arthritis, rheumatoid arthritis, fibrositis, and neuralgia.
