Lots and lots and lots of water and a few ibuprofen (advil) wouldn't hurt!! If it is a stone (and a big one, at that), you will know it...believe me!! :shock: If the pain is radiating toward the front of your abdomen, then it probably is a kidney stone! If, however, the pain is radiating down the back of your leg (on the same side), then it is the muscles and nerves in your back....if it does not let up with rest and ibuprofen you may need to see a doc...you may have done more damage than just pulling a muscle!! Be careful, get some rest and let us know how you are doing!!
