Overview of Peptic Ulcer Disease Peptic ulcer disease (PUD) is a chronic (long lasting) condition that affects the gastrointestinal (GI) tract or digestive system. PUD causes ulcers (sores or lesions) in the lining (mucosa) of the stomach or first part of the small intestine (duodenum).
What are the symptoms and how are plantar warts diagnosed? These warts can look like small, fleshy bumps; hard, flat growths with a rough surface and well-defined boundaries; or gray or brown lumps with tiny pinprick-size black dots (clotted blood vessels that distinguish warts from bloodless corns and calluses).
Your face: Flat warts and long skinny warts that look like tiny fingers usually appear on your face. The bottoms of your feet: Warts that are large flat bumps on the bottoms of your feet are very common. Plantar warts sometimes hurt when you walk on them; you might feel like you have a stone in your shoe.
