Hi, Thanks for writing in. Ringworm is a skin infection and will never cause kidney stones. However, possibility exists that if you have ringworm infection, you will have intense itching in your groin areas and this can cause other infection in the genital region, but this does not happen easily. Going to pee can be the result of minor UTI which can occur due to hygiene problems and itching. There is no reason to connect kidney stone formation and ringworm. However please continue to drink lots of water and fluids. Getting an ultrasound scan of abdomen and urine examination might help if you are having frequent urges of urine and pain in back. Hope this helps
