Ive never had sciatic pain in my life and ive been in NYC the last few days so i have been walking a lot...tonight im having the worst pain in my tailbone area shooting down my right leg! Its so miserable i cant even find a comfortable laying position...any advice? Ive been doing pidgeon pose and laying down with ankle on opposite knee stretch for a while and it helps while doing the stretches but then the pain comes right back after...im 16w today.
