Lumbar tuberculosis abscesses are usually in the bone tissue of the lumbar spine, not under the skin. Most lumbar tuberculosis abscesses are caused by the tubercle bacillus from tuberculosis reaching the bone tissue with the bloodstream, destroying the bone and then developing into bone tuberculosis. The tubercle bacillus tends to stay in the lumbar spine, so it is more common in the lumbar spine and develops in the bone tissue rather than under the skin. The symptoms of lumbar pain are often accompanied by tenderness and aggravated by coughing and exertion. When the abscess is gradually serious, the swelling of the lumbar vertebral joints will also gradually increase, and the pain in the joint area will be more obvious, and even the manifestation of joint deformity will occur, which will affect the movement of the joints. When tuberculosis patients have the above symptoms, they should seek medical treatment immediately and follow the doctor’s instructions for examination and treatment to avoid further aggravation of the condition, which will affect their daily life.
