Thank you for the query. I would like to know your age and whether you suffer from Diabetes mellitus. Since, you have a 6 month old baby, i would also like to enquire whether it was a normal delivery or Caesarian section was required. Vaginal candidiasis (yeast) is a common condition. It can lead to severe irritation, itching and curdy white discharge. Local vaginal creams for candidiasis like Clotrimazole cream must be applied. It is also necessary to maintain hygiene and keep your private parts clean and dry. I would also advise you to go for Urine routine examination and culture, to rule out any other causes of Urinary Tract Infection. In that case oral course of antibiotics may be required (since you are lactating all classes of antibiotics cannot be used). If the problem is persistent, you should get a blood sugar profile checked and consult your gynaecologist regarding the same. Hope this helps you out.
