Skin tags are common, benign skin growths. They are typically small and soft, appearing as flesh-colored or slightly darker protrusions from the skin. A common question is whether they contain nerves and can cause pain. This article clarifies their structure and explains why discomfort might occur.
Understanding Skin Tags and Their Structure
Skin tags, medically known as acrochordons, are composed primarily of collagen fibers and blood vessels, encased in epidermis. They often appear to hang off the skin by a tiny stalk, distinguishing them from other skin lesions like warts. These growths are typically small, ranging from 1 to 5 millimeters.
Generally, skin tags do not contain nerve endings. This absence is why they are typically painless unless subjected to external irritation. They commonly form in areas where skin rubs against itself, such as the neck, armpits, groin, eyelids, and beneath the breasts.
Why Skin Tags Might Cause Discomfort
Skin tags can cause discomfort or pain due to external factors. The most common reason for pain is friction from clothing, jewelry, or skin rubbing against the tag. This constant rubbing can lead to inflammation, redness, and even minor bleeding.
Accidental tugging or twisting of a skin tag, such as during shaving or vigorous activity, can also lead to pain. This action can irritate the surrounding skin or the skin tag’s base, which contains nerve endings. In some instances, a skin tag’s stalk can twist sufficiently to cut off its blood supply, causing the tag to become painful, change color, and potentially die.
When to Seek Medical Advice
Although skin tags are generally harmless, consult a healthcare professional in specific situations. If a skin tag changes in color, size, or shape, or if it begins to bleed frequently without obvious external irritation, medical evaluation is recommended. These changes, along with persistent pain or itchiness not caused by rubbing or snagging, warrant attention to rule out other skin conditions.
A doctor can confirm the diagnosis, ensuring the growth is a benign skin tag and not another type of skin lesion. If a skin tag causes significant physical irritation that impacts daily life, or if there are cosmetic concerns, a healthcare provider can discuss safe and effective removal options.
