DD2 keeps getting UTIs - pain on urinating and excessive weeing (over 200mls at times and can wee 5 or 6 times in a few hours). She has been referred for a bladder scan to rule out kidney reflux. She does drink a lot but it doesn't seem enough to fuel the huge wees she does 
She has now got thrush, could that be causing the excessive weeing or is it just because of the anti-biotics?
She does have Juvenile Idiopathic Arthritis, hypermobile joints, gastritis, ezcema and asthma so takes a cocktail of drugs/creams/inhalers. She has just started prednisolone steriods - could they have triggered the thrush?
