question: I have had several uti s, but alot of them are not. I will urniate blood and clots and have the symptoms of one. it will last a couple of hours, then it is clear and normal. The same thing may happen the next day, then no problems for weeks. What could be causing this? I have cancer but is carcinoid not bladder . I am getting frustrated, and concerned since alot of them are not uti s. Thank you
