Pain in my left thigh

So over the weekend I had a couple charley horses in my left leg which is strange because it's usually in my right leg. Anyways they stopped happening but now I have this weird feeling in my upper left thigh. It doesn't hurt too much it just feels like it might go asleep or that I'm not using it too much. It feels funny. But it usually only feels funny if I'm standing too much or sitting too much. Any idea on what it is or what I should do? I'm totally lost.
