In season EMS ?

I stimmed my hamstrings on sunday after my speed session, and now, my hamstrings are still tight and I have a race tomorrow… ROM isn’t affected very much, it’s just a feeling of tightness, and sensitivity when foam rolling.

What can I do other than EMS 5hz and some light foam rolling/showers to prepare for tomorrow in the best way possible and is it wise to PNF in the warmup before the race.

Thanks !
