I have gone to see a doctor about discomfort (itching) outside the vagina. she prescribed a vaginal cream and some antibiotic. it's been a week now and the itching is still there?

Re-exam: This is actually a common problem. Sometimes the correct infection is diagnosed and the treatment just takes longer to have an effect. Sometimes a stronger treatment is needed. And sometimes the problem may be different and require a separate treatment. Especially in this situation different infections or irritations can look similar but be treated in different ways
