For the diagnosis of lumbar muscle strain, it is mainly based on symptoms, physical examination, or combined with imaging studies. The typical symptoms of lumbar muscle strain include soreness or swelling pain in the lower back, which worsens with exertion and lessens with rest. Patients are also unable to persist in activities that involve bending over. During a physical examination, tender points in the lower back may be found, or imaging studies can be used to rule out other lumbar spine conditions. Under these circumstances, a diagnosis of lumbar muscle strain can be made. Patients with lumbar muscle strain should pay attention to rest, and can use anti-inflammatory pain medications, combined with heat therapy, physiotherapy, massage, and blocking methods for treatment, which generally can effectively improve symptoms and promote recovery. (Specific medication use should be under the guidance of a doctor.)
