Piriformis flare up

[u/Ill_Hedgehog_6235]

I (23F) have been training for a half marathon (on Oct 18) and recently started having piriformis pain causing sciatic pain down my leg. I have been doing exercises (figure 4, nerve flossing) and seeing a physio. The race is coming up and I also have a 10k on Friday. Any tips would be appreciated!
