What Relieves Severe Pain In The Hips And Thighs?

I am 23 years old, 5'9" and 120 lbs. I fell down earlier this week and landed extremely hard on the concrete. I have horrible pain in my hip/thigh area, but it only hurts when something touches it.. Even a very light object such as a towel. There is no visible bruise, but it hurts worse than any other bruise I have ever had. I can still walk and sit, but I cannot lay on my side and even the slightest touch to it makes me nauseous and feeling like I am going to pass out. I have also been sweating a lot which is very unusual for me since I am always cold. Could this be something more serious than a bruise?
