Emp acting weird - read post - is it normal or is something wrong?

My emp, just got her a couple days ago, well, earlier on my old viv she was climbing around, and hanging onto a little ledge thing, and wouldn't come off, then fell to the viv floor an inch --NOT SURE IF THAT IS A CAUSE OR ANYTHING just mentioning it.
Anyway, now, her left claw seems to not be functioning, as the right one is out, and the left one is sorta curled inward, and just right now, she's laying there with her right legs spasming out and her left legs doing nothing o.o almost as if she were trying to walk, but left side not cooperating?
I don't know, I'm new to scorpions and I'm scared something may be wrong with her. D:

wow and 3 minutes later she walks away like nothing happened l: do they do weird stuff just to worry me? lol

Can you tell us a bit more about your setup?
Humidity and temp?

Right now I have a 50w red heat light, my choices were 50 or 75 and I didn't wanna fry him. Temp gauge says 80 and is in the middle of tank (5.5g tank) humidity says 65 and I'm having a hard time keeping that up. I could post a pic of my setup on imgur? The problem went away, however he still holds his left claw weird

Yes I switched from her to him because the pet store sexed it wrong, checked myself and is male
