Go see a DR & have him/her take X-Rays and finalize the situation. Be sure that you don't have a break. You sound as though you do not know, therefore you should exhaust any and every opportunity to cease the pain. See a DR ASAP.
If you don't, you will go down a long road of pain and possibly internal damage. I have been down this road before. You want to be 100% sure. Even if it's only a fracture, at least you know and can take the proper precautions.
