I have a friend who is having the exact same thing and she's 6 months out, so hang in there. She's doing massage. My leg got straightened out too and I've had only a little bit of that lateral pain, so I'm lucky. But then again, I pretty much avoid anything that aggravates the knee. It's possible your IT band is adjusting to the change in alignment. It goes down the outside of your leg and adds structural support and is very fibrous, not stretchy, so I haven't been convinced stretching it will change anything and am letting it adjust in its own time. I think you may experience some relief of symptoms if you stop PT. Better to focus on activities that add to your happiness. I am finding, at 3.5 months, that the tissues are just cranky. I will take some measures to strengthen and tone later, when the tissues are less cranky.
