Hi i have had a bad cough lately and today while urinating i had a particularly rough cough, which inturrupted my stream and caused a brief sharp pain, thought nothing of it. a few hours later i returned to the bathroom everything seemed normal but while urinating i noticed the pain in the same place, and afterwards blood began to come out of my urethra, the blood did not mix with the urine at all it seems to happen after the fact, i just returned from the bathroom with the same results, any idea what i could have done?
