Pulled vagina muscle?

Okay, so obviously it's not my vagina. However, I'm not schooled on my muscle anatomy and I'm just referring to that region. 
Back story: I'm a teacher and went into work today to arrange my classroom. Mostly pushing desks around and placing students seats. None of it felt too strenuous and I felt fine. By the later evening - 5:30pm I was definitely feeling sore in general (mostly on my right lower side) and was waddling a lot. By 6:30 I was having sharp pain in my right side, close to my groin, by my vagina and upward toward my pelvis. 
I can't walk without holding on to something. Moving my right leg causes shooting pains. Bending over hurts. And doing nothing I have a constant dull and achy pain associated with right side lower back pain. I'm trying so hard to just go to sleep right now but the pain is getting distracting. Is this just a really bad pulled muscle? Something different? And what can I do??
