Pain in the hip while resting with a history of injury in the hip might be due to minor capsular tear or an inflammation of the articular cartilage
An examination by an orthopedician and investigations like MRI of hip will help in determining the soft tissue
Meanwhile you can do a hot fomentation, apply local analgesic
gel on the area and have a mild pain killer like acetaminophen
I hope this information has been both informative and helpful for you.
