"It is very important to talk with your doctor if you are having issues when leaving your house or going to a public place. Often, they have strategies to help you as they have helped many other patients in your situation. Something that has helped other patients is planning your itinerary in advance. Be very practical. Learn where the rest rooms are located in restaurants, shopping areas, on a trip, or while using public transportation. Always carry extra underclothing or toilet tissue in case of sudden need. Try to be matter-of-fact about your needs and your attacks of pain. In this way, you will be able to help yourself and gain cooperation from others because they will follow your lead and understand. Learning more about how your body reacts to certain food groups also may be a big help."
