How To Manage My Injured Hip?

Im 18 years old and I do tae kwon do competitively. However recently I have been injuring my hip. I am able to move it sideways and backwards but i pysically cant raise my leg even if i try to work through the pain. After a few days if i rest it it gets better but i keep reinjuring it what can i do to manage this? I dont have the option of long down time currently with my tae kwon do schedule.
