Use a heating pad. A heating pad placed on your lower abdomen can soothe and possibly minimize feelings of bladder pressure or pain. Stay hydrated. Drink plenty of fluids to keep yourself hydrated. Avoid coffee, alcohol, soft drinks with caffeine and citrus juices — as well as spicy foods — until your infection clears. These items can irritate the bladder and aggravate a frequent or urgent need to urinate. Take a sitz bath. Soak in a bathtub of warm water (sitz bath) for 15 to 20 minutes to help relieve pain or discomfort.
