Hello sir/ ma'am, from the past few months I was having gastric problem and headache, so i went to a physician and he told me to do a ultrasound and there (2 days) ago I have diagnosed 9mm calculus in lower pole calyx of right
kidney, but till now i don't have any pain or something, He gave me a cystone tablet wit some gastric related tablets for one months. I'm very nervous because I fear a lot from operations. What should I do? I'm very nervous.
