While I was asleep last night, I woke up at about 4 with lower right side back pain. It went away in a minute or two and I woke up fine. I feel ok now, but my mom scared me by saying "It might be a kidney stone" I'm an average soda drinker, and I know people that drink at least a liter a day, but are fine. Now i'm very paranoid and scared that she might be right. I don't know though, I feel ok now. Can anyone help?
