How do you handle setbacks

I'm about 1 month into my first experience with sciatica. Both legs but it can switch sides depending on the day. First two weeks were hell with most of cramps and burning butt to feet. The last two weeks I have seen improvement with walking and standing as much as I would need to. Burning left and wet sensations came in.

​

However, I re-aggrevated my back yesterday while driving and i felt that low back burning that eventually caused burning in my hamstring and calf. I tried laying down on the stomache and decompression from a bar. It seemed to help but sitting today has been much worse than it was previously. It's exhausting to think about whether or not I set myself back in my recovery.
