Hi, My 4.5 years old son has been complaining of itching in his penis. On checking we find that tip is red and inners skin is also red in parts. He has been complaining of this problem for last month and a half. This also causes him pain while passing urine. he has been taken to doctor twice for this condition and has been referred urine tests. While 1st time, he had urine infection which was duly treated, second time infection was not discovered. Could it be a hygeine issue? We have been trying to be regular in cleaning his penis when he takes bath..Is it a possibility that he may be having allergy to some clothes (like his swimming trunks ) which are synthetic? Could it be because of frequent swimming etc as he is swimming 3 times in a week for about an hour?
Itching in urethra is might be due to 1, urinary tract infection 2, improper hygiene 3, deny Chat Doctor.  In your case, the chemical in swimming pool can also cause itching. But most common is infection. Get evaluated again with urine examination and microscopy for pus cells.
