The first was the worst because you don't know what it is. Subsequent stones didn't seem to be as bad, since I knew I was going to survive.
The emerg doc told me that some ladies say the pain worse than childbirth.
That does not mean the later ones were less painful, but knowing what to expect, recognizing the symptoms early, and getting mentally ready go a long way. A well stocked medical cabinet with potent pain killers is a must, and I don't take long trips without them either.
Unfortunately, not all will pass naturally, depending on size and shape, so I'm looking forward to having this option available when needed.
