no visible bruise but bruise-like pain?

I recently slipped on ice and fell on my hip and forearm. My arm is fine, but over a day later I don't have any discoloration from bruising on my hip, but I feel pain in what feels like a mid muscle layer in my hip when I put pressure on it or when I move the muscle certain ways. It has gotten a bit better since this morning, but is still a fairly strong sharp pain at times (not too bad to keep that position, but very unpleasant) The worst is when I try to sit cross-legged or lay on that side with my leg slightly bent. When I try to sit cross legged it feels like there is swelling, but it feels like it is deeper than in the skin layer and I can't find any visible swelling. I am a 19 year old female, with fairly average weight for my height. I do not bruise easily at all, except for when a random bruise I have no explanation for sometimes shows up. I was wondering if I just bruised something deeper and missed the blood vessels right under the skin, or if this might be another issue.
