Don't wish to unduly alarm you but hip pain could be an indicator of a number of things including groin problems, poor core, hip cartilage, stress fract, bony impingements - like i said don't want to unduly alarm you but its been 8 months and you've got nowhere, time to step up asserrtiveness with professionals.
How is your core and glutes? do you work on these at all?
What does your physio say-has he done a full assessment including looking to see if any glute/core weaknesses and muscle imbalances? If physio trys to bluff this then time to change physio.
If physio can't work it out, then might wish to consider referral to Sports medicine to consider what they say, and they will likely order further investigations including MRI, possibly an arthrogram, and x-ray.
