Key points
- A vulvar haematoma is a collection of blood that pools in the soft tissues of the vulva following an injury.
- It is most commonly associated with childbirth but can occur due to falls or direct trauma.
- Symptoms typically include localized pain, visible swelling, and a purple or blue discolouration.
- Small haematomas often resolve with home care, while larger ones may require medical monitoring.
- In the UK, NICE guidelines focus on pain management and assessing the size and stability of the swelling.
- Urgent medical attention is required if the swelling grows rapidly or causes difficulty urinating.
What is a Vulvar Haematoma?
A vulvar haematoma is a localised collection of blood that accumulates within the soft tissues of the labia or the surrounding vulvar area. This occurs when blood vessels—usually small veins or arteries—are damaged, allowing blood to leak into the interstitial space. Unlike a standard bruise, which is a superficial injury, a haematoma involves a more significant volume of blood pooling, often creating a firm, painful lump.
In the UK, this condition is frequently seen in obstetric settings, particularly following a vaginal delivery. However, it can also result from non-obstetric trauma, such as a 'straddle injury' (falling onto a bike frame or gym equipment). While the appearance can be alarming due to rapid swelling and dark discolouration, most cases are manageable with the correct clinical pathway.
Common Causes and Risk Factors
The most common cause of a vulvar haematoma is childbirth. During a vaginal delivery, the tissues of the vulva and vagina are under immense pressure. Damage can occur due to:
- Instrumental delivery: The use of forceps or vacuum extraction (ventouse) can increase the risk of vessel rupture.
- Episiotomy: A surgical cut made to the perineum during birth.
- Macrosomia: Delivering a larger-than-average baby.
- Rapid second stage: A very quick delivery of the baby's head and shoulders.
Non-birth causes include blunt force trauma to the pelvic region, accidental falls onto hard objects, or complications following gynaecological surgery. In rare cases, individuals with pre-existing bleeding disorders or those taking anticoagulant medication may be more susceptible to haematoma formation following minor friction or impact.
Recognising the Symptoms
Symptoms of a vulvar haematoma usually appear quite suddenly. You may notice a feeling of intense pressure or throbbing in the pelvic region. Key signs to look for include:
- Visible Swelling: A firm, often tense lump on one side of the vulva.
- Discolouration: The skin may appear dark purple, blue, or black.
- Pain: The area is typically very tender to the touch, and the pain may worsen when sitting or walking.
- Difficulty Urinating: Large haematomas can sometimes press against the urethra, making it difficult or painful to pass urine.
If the haematoma is small, you might only feel a slight discomfort. However, larger haematomas can cause a significant drop in blood pressure if the internal bleeding is substantial, though this is rare in non-obstetric trauma.
How to Manage a Vulvar Haematoma at Home
If you have been assessed by a healthcare professional and your haematoma is deemed small and stable, you can often manage the recovery at home following NHS best practice. Treatment focuses on reducing swelling and managing pain:
Ice Packs
Apply a cold compress or an ice pack wrapped in a clean towel to the area for 10–15 minutes every few hours during the first 24–48 hours. This helps to constrict blood vessels and limit further swelling.
Pain Relief
Over-the-counter paracetamol is generally recommended. Ibuprofen may also be used if there are no contraindications, as it helps reduce inflammation. Always follow the dosage instructions on the packet.
Rest and Positioning
Avoid strenuous activity and heavy lifting. Lying on your side can help relieve direct pressure from the pelvic floor, making you more comfortable.
Hygiene
Keep the area clean and dry. When using the toilet, pat the area gently rather than rubbing. A 'sitz bath' (soaking the pelvic area in warm water) may be recommended after the first 48 hours to aid comfort, provided there are no open wounds or infections.
When to Speak to a GP Online
If you are concerned about new swelling or persistent pain in the vulvar area, you may wish to speak to a GP online for a clinical assessment. An online doctor can help by:
- Reviewing your symptoms and history (such as recent childbirth or injury).
- Providing guidance on appropriate pain relief and self-care measures.
- Assessing whether your symptoms require an in-person physical examination at a local clinic or hospital.
- Issuing a sick note if your recovery prevents you from working.
Online GPs provide a calm, factual environment to discuss sensitive health concerns. If the haematoma is small and not growing, an online consultation is a convenient way to get peace of mind and a clear management plan without leaving home.
Medical Treatment and NICE Guidance
In the UK, NICE (National Institute for Health and Care Excellence) guidelines for postnatal care emphasize the importance of monitoring any perineal or vulvar trauma. If a haematoma is large (typically over 5cm), expanding, or causing severe pain that paracetamol cannot control, hospital treatment may be necessary.
Clinical management in a hospital setting may include:
- Observation: Checking the size of the haematoma at regular intervals to ensure it isn't getting larger.
- Catheterisation: If the swelling prevents you from urinating naturally.
- Surgical Drainage: In cases of very large or rapidly expanding haematomas, a doctor may need to perform a small incision to drain the accumulated blood and tie off the bleeding vessel. This is usually done under local or general anaesthesia.
Red flags — when to seek urgent help
Call 999 or go to A&E if you experience any of the following:
- The swelling is growing rapidly in size.
- You feel dizzy, lightheaded, or faint (signs of low blood pressure).
- You are completely unable to pass urine.
- Extreme, worsening pain that is not relieved by standard painkillers.
- Signs of infection, such as pus, a foul odour, or a high fever.
