I wouldn't waste time, go to the ER. The pain is too close to the kidney and you mention swelling. Go, now.
(I do not have a medical degree) I would still listen to me though.
Sounds like a kidney infection! Get help immediately! Hopefully you already have!
Listen to Colleen.It could be kidney stone or a kidney infection.Either one you don't wan't to muck about.get to the ER.
Hope you listened to Michmar, Colleen, and Tommyh. I have the same advice. Pack a little bag.
