pitbull hurtin

Question
My pitbull's leg is hurting her but nothing has hit or bite her what's wrong with her?

Answer
I don't know what is wrong with her. I cannot see her or feel her. I need more information then what I have here. Is she limping? Is she chewing on it, licking it? Has she been outside? Is she young, old? Has she been running outside? Jumping off of furniture?
I have nothing to go on here Reggie. Sorry.
