What Is The Treatment For Frequent Urination?

my son is experiencing frequent urination and sudden urges. We had his urine tested a week ago and it was negative, although the initial test strip showed a trace of blood. However, the microscopic view showed no blood. The symptoms are still prosistent and he is beginning to be bothered by it. We were told it could be frequent daytime urination brought on by stress or change; however, he is experiencing neither. He is 5 3/4yrs old and had been potty trained and holding it through the night since 25 months old. We have never had a problem before. Should this be looked into further, could there be other causes rather than assuming it is psychological? The only other thing he has mentioned is that if pressure is applied to the abdomen from just below the belly button to about 4 finger widths down it is painful. Any insight would be appreciated. Also, he was not seen by a urologist.
