Patients with lumbar muscle strain can visit the orthopedics department. Lumbar muscle strain is primarily caused by long-term heavy physical activities involving the lower back, poor posture, and chronic strain. Symptoms can include lower back pain and restricted movement, which typically lessen after rest and worsen after physical activity. For treating lumbar muscle strain, it is important to first ensure adequate rest and to develop proper habits for using the lower back, avoiding long-term heavy physical activities. Treatment can also involve the appropriate use of non-steroidal anti-inflammatory and analgesic medications, combined with heat application, physical therapy, massage, or nerve block techniques. These methods can effectively improve symptoms and promote recovery.
