Possibly yes. They can start with the odd niggle now and then, you can pass them with just a little bit of discomfort or pain. But trust me when the big ones come the pain is nothing like childbirth, from what I've been told is a piece of piss compared to the suffering from a kidney stone.
I had a a large one make it's bid for freedom at New Years, the pain was like nothing I've ever had it had me on the floor whimpering like a baby but a baby who knew all the swear words known to man, my core temp dropped and the slightest movement was a huge effort.
I have the joy of knowing I will always produce them so have to drink loads so I pass at least 2 litres of piss a day. There will be more large ones come free, they're sitting there waiting I now have a nice stock of pain killers waiting for that day.
I've had some pain since within the a few weeks but nothing like New Years, if I don't follow my routine to well I get an ache in the kidney region either on the left or the right.
Have fun!
