Regardless of the cause, about 90% of people with sciatica will get better without surgery—most of them in just a few weeks. You can start treating your sciatica at home. In fact, home treatment may be all you need, especially if you know that your sciatica is caused by an injury or pregnancy. Even if you don’t know what’s causing your sciatica, you can take steps to relieve your pain at home. Call your doctor if the pain isn’t manageable or under certain other circumstances.
