Patient: I started t have the symptoms of cystitus last tuesday and went to pharmacy and got over the counter remedy for 48 hours. This did not help and then i went to GP who tested my urine and said there was no nfection in my urine. Prescribed trimethrepon antibiotics for 3 days (2 pills per day) and it still hasnt gone. What is wrong ? i am going to the toilet every 5 mins still
