I've been having some issues with my digestive system for a while now, counting the first incident of having haemorrhoids and having it resolved through the medicines prescribed, I had the same syptoms after a month and half. Went through ultrasound to find out that my left kidney has got some sand like formation but concluded no stones yet. There after the ultrasound showed my urinary bladder having some deposits. The doctor has only advised me to stick to liquids and bring about a change in my lifestyle. But referring to the symptoms and cross checking them over the Internet, it seems more likely thay I've had ulcer or some sort of stomach cancer. Ive been to several doctors but sadly none want to diagnose the real problem. Any help ?
