Hi - let us know how the test goes.
Provided you can find someone to help with your rehab, i would say 4-6 weeks but it could be longer depending on how you learn how to do the exercises.
I have a young guy 15yrs old with the same problem but he is back to painfree sport in less than 3 weeks with daily retraining exercises for his hip and deep abdominal muscles.
Good luck and let us know the result of the test!
