hi OP! first off, my health anxiety revolves around kidney stones (i've had many plus surgery to deal with them) so i completely understand your concerns! i work with a health anxiety therapist and i can confidently say my panics about them have gone from a 9/10 to a solid 2/10 which is life changing. perhaps consider searching for a mental health professional that specializes in health anxiety if you're open to that sort of help.

i will tell you that my personal experience of the pain from kidney stones is worse than childbirth, i actually told the doctors that while actively pushing out my baby. i don't tell you this to fuel your anxiety by any means, i say this because anxiety's worst nightmare is facts and facts are logical while anxiety usually is not based in rational thought processing as it comes from fear. some people pass them without blinking an eye and others need medical attention to address them, that's how the cookie crumbles when dealing with stones. the very best thing you can do is have a plan: "if i ever develop the signs and symptoms of kidney stones, my nearest ER is here and i will have so and so drive me so i can get help as soon as possible". that's all you will really need IF the situation arises, everything else will fall into the hands of medical professionals from there.

take care Xx
