These symptoms commonly point to a urinary tract infection (UTI) or a mild vaginal infection. Because the correct treatment depends on the exact cause, it is best to see a doctor for a quick urine test. If it is a bacterial UTI, a doctor may prescribe antibiotics like nitrofurantoin or sulfamethoxazole-trimethoprim. For temporary relief of the burning sensation, an over-the-counter urinary analgesic like phenazopyridine can help. If it is a yeast infection, antifungals like fluconazole or clotrimazole are typically used. Please drink plenty of water and consult a healthcare provider before starting any antibiotics.
