I've had dozens of stones over the last 15 yrs and I can recommend a few things that have helped me that may help you hopefully.

Obv sip water as much as possible.

Apple cider vinegar(with the mother) and real cran juice...lime cuts the cran and you can dilute both as much as you want.

Ibuprofen is your friend, booze is not.

Everyone eventually finds other things that may help but the doctors/specialists(urology) are 90% guessing as to what causes some of them and they will pretty much tell you to cut things from your diet or drink more water which if you're like me you've already went down the dark hole of the interwebs for this info.

Good luck
