The pesky thing is recurrent canker sores. They are small, shallow sores in your mouth. A stressor, weakness of the immune system, and certain foods can provoke them. Genetic predisposition may also be a reason why some folks are more prone to having them. To reduce pain, use over-the-counter ointments or gels that are intended for canker sores. Also, try to sail through stress and eat a healthy diet.

You have a dark mark left after a cold sore under your nose. A herpes simplex virus causes a cold sore. The sore is a part of the healing process, but it can leave behind a dark spot.

A tiny bump near your eyebrow is probably a cyst or a skin tag, which are common and not usually a concern. They can form from a clogged oil gland or a blocked hair follicle.
