Lumbar disc herniation can lie on your side, bend your knees and lift your hips, let your calves rest by the bed, and others help you sit up, with your calves hanging by the bed. You can also lie on your back, straighten your lower limbs, try to close your abdomen when inhaling, and relax when exhaling. Keep exercising. If the hospital doesn't work, you can call him again! I seem to have to make an appointment in advance.
