My mid right side of my back, right under my rib cage has been hurting for 5 days now?

[2/20/2009]

It hurts when I move, it is tender to the touch. I didn't notice hurting it suddenly, it just started hurting. I didn't get hit, run into anything, stretch it or pull it. I have no idea if its muscle related or something else. My Mom has had numerous kidney infections that led to having her kidney partially removed, and then had to go back and have the rest of it removed in her late 20s and I'm in my early 20s. I haven't gone to the doctor yet because I'm not sure if its nothing or what. I have no other symptoms that I know of. So I've just kind of been waiting, but it hasn't gotten any better. What do you think? I tried calling the doctors office to maybe speak to a nurse, but got disconnected. Thank you in advance! I did also just get over pneumonia in my lung right where it hurts, but I'm not sure how that could be connected at all. Thanks again.
