Introduction to the Lymphatic System
Your body's lymphatic system is a vital part of your immune defense, consisting of a network of vessels and nodes that filter lymph fluid. Lymph nodes, or glands, are small, bean-shaped structures that house immune cells to fight off infections. While there are hundreds throughout your body, the ones in your head and neck, such as the occipital nodes at the back of the skull and the post-auricular nodes behind the ears, are often the most noticeable when they swell in response to a nearby infection. A normal lymph node is typically not palpable, or at most, feels like a small, soft, and barely-there bump.
How a Swollen Lymph Node on Your Head Feels
When your body is fighting off a local infection, such as a scalp infection, ear infection, or even a simple cold, the nearby lymph nodes can swell. This is a sign that they are actively working to filter out harmful pathogens. The sensation of a swollen lymph node is distinct and can be identified by paying attention to the following characteristics:
- Size: They can feel like a small pea or bean, though sometimes they might become larger, reaching the size of a grape or small cherry.
- Tenderness and Pain: The nodes are often tender or painful to the touch. This tenderness is a result of the inflammation and immune activity happening inside the node. Pain can also occur with certain movements, like turning your head or chewing, if the swollen node is located in the neck area.
- Consistency: A typical swollen lymph node feels soft or slightly rubbery and is movable under the skin when you gently press on it with your fingertips. It should not feel hard like a stone.
- Mobility: Infected lymph nodes are usually mobile and can be moved around slightly under the skin, distinguishing them from more concerning types of lumps that might be fixed in place.
Common Locations for Swollen Head Lymph Nodes
Understanding where to feel for these nodes can help you pinpoint the source of a potential infection.
- Occipital Nodes: Located at the base of the skull, just above the hairline. Swelling here is often linked to scalp infections, head lice, or conditions like ringworm on the scalp.
- Post-auricular Nodes: Found behind the ears. These can swell due to ear infections, conjunctivitis, or infections of the scalp near the ear.
- Submandibular and Submental Nodes: Situated under the jawline and chin. These are commonly affected by sore throats, tooth abscesses, and upper respiratory infections.
When to Be Concerned: Benign vs. Worrying Swelling
While most swollen lymph nodes are a benign and temporary response to infection, certain characteristics may signal a more serious condition. It is important to pay attention to how a swollen lymph node feels over time.
| Characteristic | Benign Swollen Lymph Node (Infection) | Concerning Swollen Lymph Node (Cancer) |
|---|---|---|
| Feel | Soft or slightly rubbery | Hard, firm, or rubbery (like a rock) |
| Tenderness | Often tender or painful to the touch | Usually painless, though can sometimes be painful |
| Mobility | Movable; slides under your fingers | Fixed or matted together; does not move freely |
| Growth | Enlarges and then subsides over days or weeks | May continue to grow or remain enlarged for weeks |
| Accompanying Symptoms | Fever, sore throat, cough, infection signs | Unexplained weight loss, night sweats, persistent fever |
Self-Care for Swollen Lymph Nodes
If your swollen lymph nodes are due to a minor infection, there are steps you can take to ease discomfort:
- Apply a warm compress to the affected area. Dip a cloth in hot water, wring it out, and apply for 10-15 minutes, several times a day.
- Consider using over-the-counter pain relievers, following package instructions. Always consult a healthcare professional before giving any medication to children.
- Get plenty of rest to allow your body's immune system to focus on fighting the infection.
- Stay hydrated by drinking plenty of fluids.
Seeking Medical Attention
While most cases of swollen lymph nodes resolve on their own, a visit to a healthcare provider is warranted if:
- The swollen nodes have no obvious cause, such as a cold or infection.
- They continue to grow or do not decrease in size after 2 to 4 weeks.
- They feel hard, rubbery, or fixed in place.
- They are accompanied by unexplained weight loss, persistent fever, or night sweats.
- You experience difficulty swallowing or breathing.

Conclusion
Feeling a lump on your head can be concerning, but recognizing what a swollen lymph node feels like is an important first step. For many, it is simply a sign that your body is effectively fighting off a common infection. However, understanding the characteristics that distinguish a normal immune response from a more serious issue is crucial. By paying attention to factors like tenderness, mobility, and persistence, you can make an informed decision about whether or not to seek medical advice and ensure you receive proper care for your health concerns.
