My son all of sudden last night began having pain in his lower abdomen and he says pressure in his penis. We went to an urgent medical care center today (they are very good by the way) and they did blood work and a urine culture. All of it came back negative. He has never been sexually active so I feel like the chlamydia test will be negative also. He is really scared that we do not know what has caused this and he says he keeps reading that it will never go away. Please help me know what doctor I need to take him to next. He describes it as feeling like a belt right below his lower belly and he feels like he has to urinate but cant. YYYY@YYYY
