I Had Thr 1 L/2 Years Ago And It Was

I had thr 1 l/2 years ago and it was very successful. It was minimally invasive technique however i still get really stiff and the front of my leg or thigh still is painful. It doesn't feel like the actual hip, it feels more like a muscle or something but its sharp. Do I need physical therapy, I am still active and don't sit around in spite of the problem.
Thank you
Evelyn
