A bump on your toe is usually one of a handful of common conditions: a corn, a bunion, a wart, a cyst, or a gout deposit. Most are harmless and develop gradually from friction, pressure, or joint changes. The key to figuring out which one you’re dealing with lies in where the bump is, what it feels like, and whether it hurts.
Corns: The Most Common Culprit
If your bump is small, firm, and sits on the top of a toe or along the outer edge of your pinky toe, it’s likely a corn. Corns are thickened plugs of skin that form where your shoe repeatedly rubs or presses against bone. They’re smaller and deeper than calluses, with a hard center surrounded by slightly swollen skin. Pressing directly on one typically produces a sharp, focused pain.
There’s also a softer variety. Soft corns form between toes, usually between the fourth and fifth, where moisture and skin-on-skin contact create friction. They look whitish and feel rubbery rather than hard. Both types develop because of pressure, so they tend to show up when you wear tight or narrow shoes, or when a toe sits at an odd angle and grinds against its neighbor.
Bunions and Bunionettes
A bunion is a bony bump that develops at the base of your big toe, right where the toe meets the foot. It forms when the big toe gradually angles inward toward the second toe, pushing the joint outward. The bump itself is bone, not a growth on top of the skin, which is why it feels hard and immovable. Over time it can cause the overlying skin to become red, swollen, or calloused.
A similar bump on the outside of your foot near the base of the pinky toe is called a bunionette (or tailor’s bunion). It develops through the same mechanism, just on the opposite side. Both tend to worsen slowly over months or years and are aggravated by shoes that crowd the toes.
Warts on the Toes
Warts are caused by the human papillomavirus and can appear anywhere on the foot, including the tops and sides of toes. They’re often mistaken for corns because they’re firm and skin-colored, but a few features set them apart. Warts interrupt the normal lines of your skin. If you look closely, you’ll notice the tiny ridges that make up your skin pattern stop at the edge of the bump rather than flowing through it. You may also see tiny black or dark red dots inside the lesion. Those are clotted capillaries, the small blood vessels the virus recruits as it grows, and they’re the single most reliable visual clue that you’re looking at a wart rather than a corn or callus.
Warts can be flat or slightly raised, and they sometimes cluster in groups. They’re generally not painful unless they’re on a weight-bearing surface or get pinched inside a shoe. Unlike corns, they can spread to other toes or to other people through shared surfaces like shower floors.
Cysts Near the Toe Joint
A round, dome-shaped bump near a toe joint, especially on the top of the toe close to the nail, could be a mucous cyst. These are a type of ganglion cyst that develops from the joint capsule and fills with a thick, clear-to-yellowish fluid. In a large surgical study of foot lumps in North Glasgow, ganglion cysts were the single most common diagnosis, accounting for 39 out of 101 surgically treated lesions.
Mucous cysts are firm to the touch, not very mobile, and tend to grow slowly. They usually sit slightly off-center on the top of the toe because the tendon running down the middle pushes them to one side. One distinctive sign: if the cyst is close to the base of your toenail, it can press on the nail root and cause a visible groove or ridge running lengthwise down the nail. They’re generally painless unless they get bumped or irritated.
Gout: A Painful, Swollen Toe
If your bump appeared suddenly, is extremely painful, and your toe looks red and swollen, gout is a strong possibility, especially if it’s your big toe. A gout attack happens when uric acid crystals accumulate inside a joint, triggering intense inflammation. The pain often starts at night and peaks within the first 4 to 12 hours. The joint can become so tender that even the weight of a bedsheet feels unbearable.
Gout that goes untreated over time can produce a different kind of bump: tophi. These are chalky deposits of uric acid crystals that form under the skin near joints, including on the toes, fingers, and Achilles tendons. Tophi aren’t usually painful on their own, but they can become swollen and tender during flare-ups. They feel firm and lumpy, and in some cases you can see a whitish or yellowish color through the skin.
Hammertoe and Joint-Related Bumps
Sometimes the bump isn’t really a growth at all. It’s the joint itself, pushed upward by an abnormal bend in the toe. Hammertoe causes one or more toes to curl downward at the middle joint, creating a raised hump on the top of the toe. That raised joint then rubs against your shoe, which can produce a corn or callus on top of it, making the bump look even larger. Hammertoe develops gradually from muscle imbalance, tight footwear, or nerve damage, and the toe may eventually become rigid in its bent position.
How to Tell Them Apart
Location and texture are your best starting clues:
- Top of a toe, hard and flat: likely a corn, especially if it sits over a joint
- Between toes, soft and whitish: soft corn
- Base of the big toe, bony and immovable: bunion
- Near the toenail, round and dome-shaped: mucous cyst
- Firm with tiny black dots and disrupted skin lines: wart
- Big toe joint, red and acutely painful: gout
- Top of a curled toe: hammertoe with or without a corn
Pain patterns help too. Corns hurt with direct pressure. Bunions ache when shoes squeeze them. Gout produces severe, throbbing pain that comes on fast. Cysts and warts are often painless unless compressed.
Signs That Need Prompt Attention
Most toe bumps are benign, but a few warning signs warrant a closer look. A bump that grows rapidly over weeks, bleeds intermittently, or turns into a sore that won’t heal (or heals and comes back) should be evaluated. The American Academy of Dermatology notes that melanoma can develop on the foot, sometimes in spots that are easy to overlook, and it may appear as a growing mass, especially in an area where you’ve previously injured your foot. Warmth, spreading redness, pus, or red streaks extending away from the bump suggest infection. Persistent pain that wakes you at night or doesn’t respond to basic shoe changes is also worth getting checked.
