Has anyone experienced sciatica / butt / piriformis soreness the day after doing lunges? I've been doing Jari's workouts for awhile now - took a break because of the soreness. The break helped - the soreness was gone; Started with the workout slowly, the lunges - again got very deep pain in the butt / piriformis area where the pain goes down to the calf. I use cold compresses which helps. Just wondering if anyone else has experienced the same. Have been to Physio and also had massage treatments but upon resuming the lunges - the pain comes back. Thanks!!!
