Ok so I have a hard time urinating. I feel like I have to urinate all the time. I have had this for 18 hours. I also had a few drops of urine with blood in them. Do I need to go to the Emergency Room. I am so scared I have never had anything that felt like this or hurt in my dick. It feels like I need to Pee but I barely dribble out any urine. PLease help me!!!
