KG - I don't have much time right now but I'll pipe up and say that while your local lower leg symptoms are likely a shin splint type of scenario and could be treated locally with ice, massage, taping. The hip and lower leg thing together makes me think that you could have a problem with you back that is a component of all this. If the PT hasn't checked out your back at all than you might want to ask about it. Is this a manual therapist?
I don't think it's a serious problem, nothing to worry excessively about, I'd just want to look into it to make sure you're covering all the bases.
