Hello, today I peed alot of Red and it was obviously blood,and so I called the doctor he wants me to get my kidneys and bladder ultrasounded wich is fine, he also says my pee is full of blood, less red at the doctors office but i knew it was blood bbecause the first time after I peed it looked like someone poured a glass of fruit punch into the toilet, anyway wen Iwas in the doctors office providing a urine sample i finished in the toilet and a big weird shaped black chunk came out what is it I m wondering am I dying? It doesn t hurt wen i pee nor did it wen the thing came out, iIhave pain in my lower back left side, what the Hell is that thing, I showed my doctor a picture he didn t say so Iddon t think he knew any help would be appreciated my fear is that it s kidney or bladder disease and not an infection, please help me peeing noticeable blood and some black chunk is very scary, also I m male if that helps figure it out
