In general, for patients with lumbar spondylosis, if there are no symptoms of sciatic nerve pain, lying flat is usually very effective, but it's best to sleep on a hard bed. If the patient's lumbar spondylosis has caused spinal nerve compression resulting in sciatic nerve pain, it is best for such patients to lie on their side. Side lying allows the knees and hips to bend, thereby reducing the tension on the sciatic nerve and effectively alleviating the symptoms of sciatic nerve pain. Additionally, for those with painful symptoms due to lumbar spondylosis, it is advisable to wear a lumbar support belt to protect the area.
