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).
Warts are small and thick benign growths on the skin that are caused by human papillomavirus or HPV. Plantar warts occur on the bottom of the foot, which makes them very uncomfortable to walk on â it feels like there is a stone in your shoe. They are often on the area of your feet that experiences the most pressure, which may drive the wart to grow flat but deeper under the skin.
