My 21-year old son is worried about himself and he's got me worried now, too. About a month ago he experienced burning during urination, and some bleeding. He went to his college health service, and went through the usual battery of tests, all of which returned with negative results. He also had his blood tested for Hepatitis. He was given a very short course of antibiotics, as a precaution. He told me that the burning resolved itself, and although he continued to spot blood infrequently, he didn't allow himself to worry about it too much, since he had been told he had been cleared of the usual suspects. Today he called me because the bleeding has begun again, more than before. Mark you, he has a girlfriend, and he is sexually active, and I suspect like a lot of young men, he is VERY sexually active. And he has been spending most of the past week visiting his girlfriend. What do you think? There are some very scary reasons for this ongoing bleeding, but he is a young man. Do you think if he were celibate for some time (a week, two weeks, a month?) this might be resolved? Is there anything else that the health service should be checking? Should he be getting a second opinion? Thank you, from a worried mother.
