I was admitted to hospital recently and been told I have a kidney stone in my left kidney in lower lobe. I have had very heavy blood in my urine, am experiencing very bad back pains, pains under my ribcage, feeling sick all the time, urinating a lot, pain in my lower abdomen. the kidney stone measures 9mm. I have had cystoscopy, IVP, Ultrasound and xray but have been told that the kidney stone would not be giving me such severe symptoms, what else could this be?
