My dd has recently started suffering from urine infections, she had an episode 2 weeks ago of needing to wee every 5 mins and c/o pain when she went. Saw a G.P who gave her a course of trimethoprim for 5 days and it seemed to improve and then today she has come home from school with exactly the same symptoms again 
Will take her back to G.P but wondered if anyone had any advice or ideas on why she would suddenly start getting them?
TIA
