Sorry to hear about your injury. It seems you may have injured your tensor fascia latae (TFL), which Is near your hip area on the outside thigh.
It is a band of connective tissue that stretches from the outside of the hip down to the outside of the knee/ upper leg.
You would need to see either a sports doctor/ orthopaedic surgeon. A thorough examination will be done, followed by an MRI to delineate the damage. A proper treatment plan can then be instituted to help you with the problem. Hope this is useful, and best regards!
