I noticed small amount of fresh blood coming out of my penis and I saw clotted blood threads in my urine and semen, also burning penis pain from inside "typically in penile urethra", unfortunately these symptoms lasted more than 4 months till now , I visited urologist and I've done blood tests such as PSA it was normal and urinalysis findings was RBC's , no signs of inflammation or infection, kidney tests was normal, Doctor asked for abdominal and pelvis ultra sound and nothing noticed except tiny gallstones.
I'm very worried because I felt simple pain in my lower left back when I lay down I'm scared that there is something wrong like metastatic tumor to the bone.
can anyone please tell me what are the possibilities for my case or guide me what to do next?
