Patients with lumbar muscle strain primarily suffer from back injuries due to long-term heavy physical activities involving the waist, poor posture, and chronic wear and tear, causing symptoms such as lower back pain and restricted movement. Those suffering from lumbar muscle strain should first focus on rest and develop proper habits of using their waist to avoid engaging in long-term heavy physical activities. At the same time, symptomatic treatment may include the use of non-steroidal anti-inflammatory analgesics, combined with heat application, physical therapy, massage, or trigger point injection. These methods can actively improve pain symptoms and promote recovery.
