Patients with lumbar muscle strain can generally improve their symptoms or even recover after rest or treatment. The main causes of lumbar muscle strain include long-term heavy physical activities involving the waist, poor posture, chronic strain, trauma, etc., which can cause symptoms such as back pain and limited mobility. These symptoms lessen after rest but can worsen after resuming strenuous activities. For the treatment of lumbar muscle strain, it is important first to rest and develop correct habits of using the waist to avoid long-term heavy physical activities involving this area. Treatment may include the symptomatic use of anti-inflammatory pain medications, combined with heat application, physical therapy, massage, or block therapy. These methods can play a positive role in symptom improvement and recovery. (Specific medications should be used under the guidance of a physician.)
