Firstly, general treatment is necessary, which mainly includes rest, or regularly changing posture, and avoiding bending over to lift objects. This is primarily to alleviate symptoms and prevent recurrence. Additionally, using a lumbar support belt at work can limit the range of motion of the waist and is very effective for lumbar muscle strain. Moreover, after entering the remission phase, when the pain has subsided, it is important to strengthen the muscles of the lower back. If the strength of the lower back muscles is improved, the stability of the lumbar spine will also improve, making lumbar muscle strain less likely to occur. Secondly, some physiotherapy can be applied to the painful area, including massage, manipulation, or acupuncture. Thirdly, if there are specific tender points, localized treatment around these points can be considered, which is highly effective. Fourthly, if the pain is particularly severe, affecting work and rest, or causing patient anxiety, consideration can be given to using some non-steroidal anti-inflammatory painkillers, muscle relaxants, or sedatives like diazepam. Therefore, treatment of lumbar muscle strain is essential and must be correctly administered. (Medications should be used under a doctor's guidance based on specific conditions.)
