Hi, I Am 19 Years Old And A Runner And

Hi, I am 19 years old and a runner and around 2 weeks ago I did a program called insanity and my hip has been hurting me ever since. I've been walking and trying to run but it hurts. And I've been taking Ibrufen but it's not really helping and I really want to start running 5K again. What should I take for it or do? I can't rest it! Thanks
