Hello Doctor,I am Jhon, I have seen blood marks in my underwear when I wake-up from the sleep. I was in the fast sleep and had lot of heavy work during the day. I dont have any pain in my penis. I hope we called it as night fall but this time with blood.
Hi, I had gone through your question and understand your concerns. It may not be bleeding caused by penis itself but more likely this is sign of reinfection or kidneys stones. This is mainly self limiting and doesn't require any specific treatment, and you should just be patient and have fluids to promote urination.  Less likely it may indicate possible bleeding in urethra, bladder or kidneys from popped vessel or some other cause. IF this continues you should do urinalysis, monoculture and kidneys ultrasound to rule these main causes out. You should Chat Doctor.  Also, avoid sexual intercourse and have keep good hygiene. You should reduce salt in your diet as well since this could lead to increased risk of urinary stone formation. Lastly, some prostatitis or prostate tumors may have similar signs, but this is seen in advanced age only. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
