My son is 19 years old. He feel like he needs to urinate constantly, and feels like it never all comes out. He is having trouble with his bowels also. he is extremelly active and healthy. He has 2-3 bowel movements a day and now he is only able to get small pieces out and feels extremelly bloated. he says there is no pain, but feels miserable in his whole lower region. We took him to an instacare doctor who said he had a slight bit of blood in his urine and gave him an antibiotic for a prostate infection. He has been on the antibiotics for 48 hours now, but we are not seeing any relief.
