My son is 11 years old profoundly deaf and at residential school, he has been having trouble with weeing and has been saying his "willy" is hurting when hes been home, a first urine test came back ok, then last weekend he was grumbling again so they did another test, hes now home for hols and ive had a letter saying they need to redo his test,,, i know its probably nothing but im worrying, our home doctor's surgery is going to do the test and post the results to school docs, i have faxed the letter i got sent home! Any ideas what it maybe?? Worse case scenario etc?
