I was laying in bed 2 nights ago and felt this pain in my lower right side side, more toward the front than the side, but definitely not, say, right next to the navel or anything.

Anyway, I couldn't figure out what the pain was, so I jumped up and looked in the mirror and felt for the area. There was about a peanut M&M sized lump there with discolored skin (almost like a bruise, but w/some grayish color to it, too). Today the jeans I'm wearing are a little tight on the area and it has been bugging me all day!

My doctor is closed today (Friday), so I don't know what to do!

Any ideas?
