I know what you may be going through. Had them about 15 years ago and spent 5 days in the Stuart Florida hospital. Had never been in a hospital before that. Went in not having ever used pills, came out having to take 3 different pills and still do. None associated with the Kidney Stones. They treated me for the terrible pain and I went home before it was passed but it did about 3 days after I was home. I guess it is hopeful yours was small enough to pass naturally and it is now a wait and see problem. I did not change my diet and have been lucky they have not returned !! This may be the only time you ever get them! Thoughts are with you !!
