The common symptoms of lumbar spine abscess vary according to the etiology, mainly manifested as pain, muscle spasm, toxemia symptoms, tuberculosis systemic toxicity symptoms, spinal deformity and so on. 1. Pain: most patients with lumbar abscess have obvious low back pain, are bedridden and cannot turn over. Sometimes it can be accompanied by radiating pain in the innervated area of the corresponding ganglion. 2. Muscle spasm: the pain and instability of the diseased vertebrae cause spasm of paravertebral muscles, resulting in the spine being in a fixed passive position, with limited movement and percussion pain. 3. Toxemia symptoms: vertebral septic osteomyelitis is dominated by Staphylococcus aureus infection, and the toxemia symptoms are obvious, manifesting as acute onset of the disease, with chills, chills and high fever. 4. Tuberculosis systemic toxicity symptoms: spinal tuberculosis leads to lumbar cold abscess, with tuberculosis systemic toxicity symptoms, slow onset, afternoon hot flashes, fatigue, emaciation, night sweats, lack of appetite and anemia symptoms. Children mostly show night cries, sluggishness or agitation. 5. Spinal deformity: obvious bone destruction, spinal deformity and instability, and posterior convex deformity is common. If patients have the above symptoms, please go to the hospital in time to clarify the cause of the disease and get regular treatment under the doctor’s guidance, so as not to delay the condition.
