For mild sciatica in pregnant women, it can heal spontaneously with aggressive conservative treatment. Most of the sciatica in pregnant women is due to prolonged sitting during pregnancy or compensatory protrusion of the lumbar region due to the increase in abdominal weight, which causes posterior protrusion of the intervertebral disc to compress the spinal nerve root and produce sciatica pain. Pregnant women should pay attention to avoid prolonged sitting and standing, sleep on hard beds as much as possible, and do not recline on sofas or beds to watch TV or play with cell phones. For sciatica that has already formed, you can often perform straight leg elevation exercise, downward pressure on the affected limb to pull the sciatic nerve, thus relieving the pain, and you can also combine some microwave, baking lamp and other physical therapy, all of which can help relieve the symptoms. Only the more serious sciatica produced by lumbar disc herniation requires further invasive treatment at a later stage.
