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).
The symptoms of plantar warts include: Dark spots on bottom of foot, also known as black pinpoints which are tiny clotted blood vessels. A callus of thickened skin over a well-defined area where a wart is growing inward. A small, rough and grainy lesion on the bottom of the foot. A lesion that stands out among the normal lines of the foot.
