Common Causes of Lumps on the Head
There are numerous potential causes for a lump developing on the head, ranging from completely harmless conditions to those requiring medical attention. Correctly identifying the type of lump is the first step toward finding the right treatment.
Injuries: The Common "Goose Egg"
After a blow to the head, a bump known as a hematoma or “goose egg” often forms. This is caused by blood vessels breaking under the scalp, leading to localized swelling. The scalp is rich in blood vessels, which explains why these bumps can appear and swell so quickly.
- Appearance: A prominent, swollen area, often with bruising.
- How it feels: Firm and swollen, sometimes tender to the touch.
- Resolution: Most goose eggs resolve on their own within a few days or weeks with proper home care.
Cysts: Fluid-Filled Sacs
Cysts are sacs beneath the skin filled with fluid or a cheese-like substance (keratin). The most common types found on the scalp are pilar and epidermoid cysts.
- Pilar cysts: Form around hair follicles on the scalp and tend to be smooth, dome-shaped, and skin-colored.
- Epidermoid cysts: Often found on the face and neck, but can occur on the scalp. They are slow-growing, small, and firm lumps.
- Appearance: Often a visible lump, sometimes with a small central pore.
- How it feels: Firm and stationary; infected cysts can be red, tender, and warm.
Lipomas: The Fatty Lump
A lipoma is a slow-growing, benign (non-cancerous) tumor made of fat tissue. They are one of the most common soft tissue tumors but rarely occur on the head.
- Appearance: A small, round, or flattened lump just under the skin.
- How it feels: Soft, doughy, or rubbery, and can be moved easily with slight finger pressure.
- Treatment: Usually harmless and doesn't require treatment unless it's painful, growing rapidly, or for cosmetic reasons. In that case, surgical removal is an option.
Folliculitis and Boils: Infected Hair Follicles
Folliculitis is the inflammation or infection of hair follicles, leading to red, pus-filled bumps. A boil is a deeper, more severe form of folliculitis.
- Appearance: Red, swollen, and pimple-like or pus-filled.
- How it feels: Often painful, tender, and warm to the touch.
- Treatment: Mild cases might clear up on their own, but more severe cases often require antibiotics or drainage by a doctor.
Swollen Lymph Nodes
Lymph nodes, part of the body's immune system, can swell in response to an infection. The occipital lymph nodes are located at the base of the skull and can become noticeable when swollen.
- Appearance: Pea or bean-sized, oval lumps of tissue.
- How it feels: Tender, soft, or sometimes rubbery.
- Treatment: Swelling typically subsides as the underlying infection resolves. A doctor's visit is recommended if they persist or have no known cause.
Osteomas: Benign Bone Growths
An osteoma is a slow-growing, non-cancerous bone tumor that can form on the skull.
- Appearance: A hard, bony, and fixed lump.
- How it feels: Hard to the touch and does not move.
- Treatment: Often requires no treatment unless it causes symptoms like headaches or sinus issues by pressing on nerves.
When to Seek Medical Attention
While many head lumps are harmless, it’s crucial to know when to see a doctor. Seek medical help if you experience any of the following:
- The lump appeared after a severe head injury and is accompanied by concussion symptoms.
- The lump is growing rapidly or changes in shape.
- It is unusually painful or tender.
- You notice discharge, pus, or bleeding from the lump.
- The lump feels hard, is immobile, and does not move when pressed.
- You have other systemic symptoms like fever, night sweats, or unexplained weight loss.
Comparing Common Head Lumps
Knowing the characteristics of different lumps can help you determine the cause, but a professional diagnosis is always recommended.
Feature | Goose Egg (Hematoma) | Cyst (Pilar/Epidermoid) | Lipoma | Swollen Lymph Node |
---|---|---|---|---|
Cause | Head injury | Blocked follicle, trauma | Excess fat cells | Infection (immune response) |
Appearance | Swollen, bruised | Dome-shaped, skin-colored | Rounded, flattened | Oval-shaped, pea-sized |
Texture | Firm, swollen, tender | Firm, stationary | Soft, doughy, mobile | Soft, tender, movable |
Growth | Rapid onset | Slow-growing | Very slow-growing | Varies (depends on infection) |
Diagnosis and Professional Evaluation
A doctor can typically diagnose a head lump through a physical examination and by asking about your medical history. In some cases, to ensure a proper diagnosis and rule out more serious issues, they may recommend additional tests:
- Imaging Scans: A CT scan or MRI might be used to get a detailed view of the tissue or bone beneath the scalp.
- Biopsy: A small tissue sample from the lump may be taken for analysis in a lab, especially if a malignancy is suspected.
Treatment Options Based on the Cause
Effective treatment for a head lump is dependent on its cause. Getting rid of a lump on your head is not a one-size-fits-all process.
For Minor Injuries (Goose Eggs)
- Apply a cold compress: Use an ice pack wrapped in a cloth for 15–20 minutes several times a day to reduce swelling.
- Rest: Avoid activities that could cause another head injury.
- Over-the-counter pain relief: Acetaminophen can help manage pain and discomfort.
For Cysts
- Watch and wait: If the cyst is small and not bothersome, it may not need treatment.
- In-office procedure: A doctor can drain an infected cyst or perform a surgical excision to remove the entire sac and prevent recurrence.
For Infections (Folliculitis/Boils)
- Medication: Antibiotics (oral or topical) can be prescribed to clear the bacterial infection.
- Warm compress: Applying a warm compress can help bring the infection to a head and encourage drainage.
For Lipomas and Osteomas
- Observation: Many lipomas and osteomas require no treatment at all and are simply monitored for changes.
- Surgical removal: If the lump is growing, causing pain, or for cosmetic reasons, a surgeon can remove it.
The Critical Importance of a Professional Evaluation
Attempting to treat a head lump without a proper diagnosis can be dangerous. For instance, self-draining a cyst can lead to a more severe infection. Similarly, assuming a hard, immovable lump is harmless can delay the diagnosis of a more serious, albeit rare, condition.
Consulting a healthcare professional is the safest and most effective way to address concerns about a head lump.

Conclusion: A Proactive Approach to Health
Discovering a lump on your head can be unsettling, but armed with the right knowledge, you can approach the situation with confidence. By understanding the possible causes and recognizing when to seek professional medical advice, you can ensure a correct diagnosis and receive the appropriate treatment. Always prioritize safety and consult a doctor, as attempting to get rid of a lump on your head without professional guidance is risky.
