Provoking Step / IT band

After the lesson this week the next day I felt some pain/soreness on the side of my leg beneath my knee. I also remember one of the times doing the provoking step when I was torqueing my body I felt a big stretch on the butt and I think that rep may have been the time that really stretched whatever was on that side of the leg. Is it normal to have soreness around this part of the leg when doing the provoking step or was I doing it wrong?
