Introduction
In general, when a person has a herniated disc, whether to support the lower back or the legs while lying down should be determined based on the patient's main symptoms. During episodes of pain, appropriate rest is necessary; however, prolonged bed rest may lead to muscle atrophy and stiffness. Therefore, moderate activity is also important. It is recommended to engage in appropriate physical activity under the guidance of a doctor or physical therapist.
Generally, when a patient has a herniated disc, whether to place support under the lower back or under the legs while lying flat should be determined based on the patient's primary symptoms. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:
1. Lying flat with lumbar support
If the patient primarily experiences lower back pain and leg pain, it is recommended to lie flat with support under the lower back. A herniated disc may cause the disc to protrude backward and alter the natural curvature of the spine, thereby compressing the lumbar nerve roots and causing lower back and leg pain. Placing support under the lower back while lying down provides additional stabilization, helps maintain the spine’s normal curvature, reduces pressure on the lower back and the compressed nerve roots, and thus alleviates pain.
2. Lying flat with leg elevation
If the patient primarily suffers from leg edema and varicose veins, it is recommended to lie flat with the legs elevated. A herniated disc may compress the lumbar nerve roots or veins, impairing blood circulation in the lower limbs and leading to symptoms such as leg swelling and varicose veins. Elevating the legs while lying down increases leg height, reduces resistance to venous return, promotes blood circulation, and improves these symptoms. Additionally, leg edema and varicose veins can negatively affect sleep quality; elevating the legs helps improve sleeping posture and enhances overall sleep quality.
Rest is necessary during acute pain episodes, but prolonged bed rest may lead to muscle atrophy and stiffness. Therefore, moderate physical activity is also important. It is recommended to engage in appropriate exercises—such as walking or stretching—under the guidance of a physician or rehabilitation specialist to maintain muscle flexibility and strength.
