I can tell you that right now, as I still have tendonitis in my left hip
and my hip flexors and adductors are VERY tight, that I do wake up at
least 3 times a night with a quick jerk of pain when I switch position.
It doesn't hurt when I walk now, but over night I guess I curl up into
that fetal position and then everything tightens up.  So, my
answer...sounds logical to me that she could be in some discomfort.
