Possible Broken Eye Socket!!!

About a week ago, I was out with all my friends having a couple drinks. One of my girlfriends got really emotional and ended up hitting me in the face. It wasn't exactly a love tap either. I didn't really feel it at the time because I was too upset but when I woke up the next morning my eye was completely swollen and shut. It was dark purple and red, which struck me as very very odd!

I iced it for the whole weekend and the swelling went down a lot!! i still have a black eye around my eyelashes almost like I have eyeliner on and under my eye is still black.

What concerns me is the top of my eye, my eybrow area to be exact. There is a lump in it that is about the size of a peanut and is sore to the touch and when I look around. I am in a lot of pain and I don't know if I should go and get xrays or not. I have taken pain releif but it is not helping. Do I have a broken bone??

Any help would be great!!
