I woke up with it one night back in 2019 (my right leg was on fire and it had that feeling of stretching too far even while just lying there normally). My foot got a little tingly for a few weeks after that as well. It comes and goes here and there. The one thing I have noticed that reduced the frequency (along with general lower back pain) was quitting drinking altogether. I gave up drinking 5 years ago and I rarely get back pain or sciatica. Drinking causes inflammation, which is bad for any injury.
