The labium majus, commonly known as the outer lips of the vulva, are two prominent folds of skin that surround and protect the other external female genital organs, including the clitoris, vaginal opening, and labia minora (inner lips). They play a crucial role in shielding sensitive tissues from irritants and infections.
Vulvar pain refers to discomfort or pain in the external female genitalia, which includes the labium majus. This pain can range from mild irritation to severe, persistent discomfort and can affect daily activities and overall quality of life.
Pathophysiology of Labium Majus Pain
Structure
The labium majus are composed of fatty tissue, connective tissue, sweat glands, and hair follicles. They are covered by skin that is similar to the skin on other parts of the body but is more sensitive due to a higher concentration of nerve endings.
Blood Supply
Blood to the labium majus is primarily provided by the vulvar arteries, which branch from the internal and external iliac arteries. Adequate blood flow is essential for tissue health and healing.
Nerve Supply
The labium majus receive nerve signals from the pudendal nerve, which transmits sensations such as touch, pain, and temperature. This nerve supply makes the labium majus highly sensitive to external stimuli.
Types of Labium Majus Pain
Labium majus pain can be categorized based on its nature and underlying causes:
- Acute Pain: Sudden onset, often due to injury or infection.
- Chronic Pain: Persistent pain lasting longer than three months, possibly due to nerve damage or chronic conditions.
- Localized Pain: Pain confined to a specific area within the labium majus.
- Radiating Pain: Pain that spreads from the labium majus to other areas of the vulva or surrounding regions.
- Burning Pain: A sensation of burning, often associated with infections or skin conditions.
- Sharp Pain: Intense, stabbing pain, possibly from trauma or certain medical conditions.
- Dull Ache: A constant, low-level pain that may indicate underlying inflammation or chronic issues.
