Hello, welcome to Healthcaremagic. First of all you need to inform me about your gender. In case it seems to be a case of cystitis
which can occur due to infection. But it could also be due to several other reasons like renal stones
or UTI. There can be different presentation of UTI which may not necessarily involve burning micturition. You must visit a urologist
to get diagnosis and further treatment. Till than you must drink plenty of fluids as it can help you flush out some of infective agents. Wish you good health.
