<s>[INST] hello, I am a male. when I went to pee this morning, I was met with a burning sensation and began urinating, and peed out blood. this has gone on throughout the day.  Just about an hour ago I went to thhe bathroom and urnatid what seemed to me like an inch long worm. it was elastic. since then I have urinated and everything is back to normal. what happened? [/INST] Good Day, and thank you for being with Chat Doctor ! You have passed out a blood clot. That is the elastic worm like structure you have urinated. I would suggest getting an urinalysis and a kidney unitary bladder ultrasound to check and rule out malignancy in the genitourinary tract. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/ Chat Doctor.  Best wishes </s>
