You can check your lymph nodes at home using the pads of two or three fingers, pressing gently in small circular motions over the areas where nodes sit close to the skin. The main spots to check are your neck, behind your ears, under your jaw, above your collarbones, in your armpits, and in your groin. A normal lymph node is small (under 1 cm), soft, and moves freely when you press on it. Anything larger, harder, or fixed in place is worth paying attention to.
Where Lymph Nodes Are Close Enough to Feel
You have hundreds of lymph nodes throughout your body, but only certain clusters sit near enough to the surface to check by hand. The locations that matter for a self-exam are:
- Behind the ears and base of the skull: small clusters tucked along the hairline and behind each ear
- Under the jaw and chin: nodes that run along the jawbone on both sides
- Sides of the neck: chains running from below the ear down toward the collarbone
- Above the collarbones: nodes sitting in the hollow just above each collarbone
- Armpits: a cluster deep in each armpit
- Groin: nodes along the crease where your leg meets your torso
Nodes deeper in the chest, abdomen, and pelvis can’t be felt from the outside. Those only show up on imaging like a CT scan or ultrasound.
The Basic Technique
Use the pads (not the tips) of your index and middle fingers, or add your ring finger for broader coverage. Press with a light, gentle touch and move your fingers in small circles. You’re trying to roll the tissue under the skin against the underlying muscle or bone. Too much pressure can push a node out of reach or make it hard to distinguish from surrounding tissue.
After feeling one spot, shift your fingers slightly and repeat, because nodes form chains and strands rather than sitting alone. Check each area two or three times to cover the full cluster. The most useful habit is to check both sides at the same time (or one right after the other) so you can compare. A node that feels the same size on the left and right is far less concerning than one that’s noticeably larger on only one side.
Checking Your Neck and Jaw
Start under the chin and work your fingers along the underside of the jawbone toward your ears. Then move to the sides of the neck, feeling from just below the ear down to the collarbone. When you’re checking one side, tilt your head slightly toward that same side. This relaxes the neck muscle and makes it easier to feel nodes that would otherwise hide beneath taut tissue.
Don’t forget the back of your head. Run your fingers along the base of your skull where your neck muscles attach. Nodes here often swell with scalp infections or head colds.
Checking Above the Collarbones
This area deserves special attention. Hunch your shoulders forward and bring your elbows in toward your body. This relaxes the skin and muscle over the collarbone, opening up the small hollow where supraclavicular nodes sit. Press gently into that space on each side.
Swollen nodes above the collarbone carry more clinical weight than swelling in other spots. A persistently enlarged node on the left side above the collarbone has a well-documented association with cancers originating in the abdomen or pelvis, a connection first described in 1848 and confirmed in studies since. On either side, swelling here can also signal problems in the chest. If you feel something firm in this area that wasn’t there before, it’s worth getting checked promptly.
Checking Your Armpits
Axillary nodes sit high and deep in the armpit, so you need the arm on that side to be relaxed. If you’re checking your left armpit, let your left arm hang loosely or rest it on a table. Reach across with your right hand, cup your fingers into the armpit, and press gently upward against the chest wall. Roll your fingers in small circles, feeling for anything round or firm. Repeat on the other side. These nodes commonly swell after minor hand or arm injuries, skin infections, or sometimes after vaccinations in that arm.
Checking Your Groin
Lie on your back with your legs straight or knees slightly bent. The inguinal nodes run along the crease where your thigh meets your lower abdomen. Use two or three fingers to press gently along this fold on each side. It’s normal to feel small, pea-sized nodes in the groin, especially if you’ve ever had a cut, blister, or infection on your legs or feet. What you’re looking for is a change: something new, larger, or harder than what’s been there before.
What Normal Nodes Feel Like
Most healthy lymph nodes are less than 1 centimeter across, roughly the size of a pea or small bean. They feel soft, smooth, and rubbery. When you press on them, they slide easily under your fingers. Many people can’t feel their nodes at all when they’re at normal size, and that’s completely fine.
Thin people and children tend to have more palpable nodes simply because there’s less tissue between the skin and the node. Finding a small, soft, moveable node doesn’t mean anything is wrong.
Signs a Node May Be Abnormal
When a lymph node is fighting an infection, it swells, becomes tender, and the overlying skin may feel warm. This is the most common cause of noticeable lymph nodes and usually resolves on its own once the infection clears. Most swollen nodes from a cold, sore throat, or minor skin infection return to normal within a few weeks.
Characteristics that raise more concern include:
- Size over 1 cm that persists for more than six weeks without an obvious infection
- Hard or firm texture, like a marble rather than a grape
- Fixed in place, not sliding under your fingers when you press
- Painless swelling that keeps growing slowly
- Matted nodes, where several feel stuck together in a clump
Size alone isn’t a reliable way to rule something in or out. A badly infected node can swell to several centimeters and still be completely benign, while a small, hard, fixed node can be more significant. The combination of features matters more than any single measurement.
Symptoms That Warrant Prompt Attention
Swollen nodes paired with certain whole-body symptoms shift the picture. Unexplained weight loss, drenching night sweats, and persistent fevers (sometimes called “B symptoms” in clinical settings) alongside enlarged nodes are a combination that warrants a medical visit rather than a wait-and-see approach. The same is true for nodes that keep growing over weeks, nodes that appear in multiple areas of the body at once, or any palpable node above the collarbone.
What Happens if You Need Further Evaluation
A provider’s first step is a physical exam, checking the same areas you’d check at home but with a trained sense of what different textures and sizes mean. From there, a complete blood count can reveal signs of infection, immune disorders, or blood cancers. Imaging, usually ultrasound or a CT scan, gives a clearer picture of a node’s internal structure, its shape, and whether deeper nodes are also involved. If a node still looks suspicious after those steps, a biopsy (removing a small sample with a needle, or sometimes the entire node) provides a definitive answer.
The vast majority of swollen lymph nodes turn out to be reactive, meaning your immune system is doing exactly what it’s supposed to do. Checking your nodes regularly helps you learn your own baseline, so you’ll notice a real change if one ever occurs.
