Sciatica help

I’m 19w5d & was diagnosed with sciatica last night. I had two episodes, the first one I was able to just kinda walk off in about 10-15 minutes. The second one... I was literally stuck in bed for 3 hours until someone was able to come help me & take me to be seen. I couldn’t move without being in a very considerable amount of pain. It’s been almost 24 hours now & it still hurts.

I would like to avoid another episode where I’m immobile as much as possible. What are some things I can do to prevent it from happening again if any?
