For severe lumbar muscle strain, in cases where the strain is not very severe, it usually manifests as the patient primarily experiencing symptoms of soreness and pain in the lower back. For such patients, full recovery is still possible with active cooperation in treatment. First, it is necessary to reduce local irritation by strictly resting and protecting the affected area, which is the best condition for patient recovery. It is important to avoid prolonged sitting or standing, excessive bending or lifting heavy objects. It is advisable to wear a lumbar support belt to protect the lower back and actively apply local treatments such as heat application, massage, acupuncture, and cupping. Additionally, topical application of ointments that invigorate the blood and dispel stasis can also be used. Most patients will gradually recover through these active treatment methods.
