A bunion shows up as a bony bump on the inside of your foot, right where your big toe meets the base of your foot. It forms when the joint at the base of the big toe shifts outward while the toe itself angles inward toward your smaller toes. If you’re noticing changes in how your foot looks or feels, there are several reliable ways to tell whether a bunion is developing.
The Visible Signs
The most obvious indicator is a protruding bump on the inner edge of your foot at the big toe joint. Stand barefoot on a flat surface and look down at both feet. In a foot without a bunion, the inner edge runs fairly straight from heel to big toe. With a bunion, you’ll see the joint jut outward, creating a noticeable bulge, while the big toe points toward or even overlaps the second toe.
Other visual changes include redness or discoloration over the bump, swelling around the joint, and skin that looks thickened or calloused on the bump itself or on the bottom of your foot near the ball. Your foot may also appear wider than it used to, especially across the forefoot. Many people first notice this when shoes that once fit comfortably start feeling tight across the front.
What Bunion Pain Feels Like
Bunion pain typically builds slowly over months or years, which distinguishes it from conditions that flare up suddenly. You might feel a dull ache or soreness at the base of the big toe that gets worse when you’re wearing shoes, particularly anything narrow or with a pointed toe box. The pain often eases when you take your shoes off or switch to something wider.
Stiffness is another hallmark. Try bending your big toe up and down. If the range of motion feels limited compared to your other foot, or if the movement produces pain or a grinding sensation, the joint is likely affected. Over time, the joint can become increasingly rigid, making it harder to push off normally when walking.
Some people also notice pain that comes and goes for no clear reason, especially early on. Intermittent soreness around the big toe joint, even on days you haven’t been particularly active, can be one of the first functional signs before the bump becomes prominent.
Early Signs Before the Bump Is Obvious
Bunions don’t appear overnight. In the early stages, the bump may be subtle enough that you’re not sure it’s there. Pay attention to these less obvious signs:
- Shoe fit changes. One shoe feels tighter than the other across the front, or you find yourself gravitating toward wider styles without consciously deciding to.
- Intermittent redness or warmth. The skin over the big toe joint occasionally looks pink or feels warm to the touch after walking or wearing certain shoes.
- Mild stiffness in the morning. Your big toe feels stiff when you first get up but loosens as you move around.
- Calluses forming in new places. Thickened skin developing on the ball of your foot or between your first and second toes suggests the big toe is shifting and changing how pressure distributes across your foot.
A Simple Self-Check
Stand barefoot on a piece of paper and trace the outline of your foot with a pen held straight up and down. Then stand normally on the tracing. If the bump at your big toe joint extends beyond the traced line, or if your big toe clearly angles toward the second toe rather than pointing straight ahead, those are strong indicators. Compare both feet, since bunions often develop on one side before the other or progress at different rates.
Next, sit down and try to move your big toe. Gently pull it away from your second toe (toward the inside of your foot). If the toe resists or won’t straighten to a neutral position, the joint has likely started to change structurally. Also feel around the bump itself. Bunions are firm and bony, not squishy. If the bump feels soft or fluid-filled, something else may be going on.
Bunion on the Pinky Toe Side
Bunions can also form at the base of your smallest toe, on the outer edge of your foot. These are called tailor’s bunions. The signs are similar: a bony bump where the pinky toe meets the foot, redness, swelling, and pain that worsens in shoes. The pinky toe may angle inward toward your other toes, and corns or calluses often develop on or around it. If you’re experiencing pain on the outer edge of your foot with a visible bump near the little toe, you’re likely dealing with this type.
How to Tell It’s Not Gout or Arthritis
Several conditions cause pain at the big toe joint, so it helps to know what sets bunions apart. The biggest clue is timing. Bunion symptoms develop gradually, over weeks to months, and the bump is always there (it doesn’t come and go).
Gout, by contrast, strikes suddenly. You might go to bed feeling fine and wake up with intense, throbbing pain in the big toe joint along with dramatic swelling and redness. Gout flares typically peak within 12 to 24 hours and then fade over days or weeks. Between flares, the joint may feel completely normal. If your pain arrived out of nowhere and is severe, gout is more likely than a bunion.
Arthritis in the big toe (sometimes called hallux rigidus) causes stiffness and pain similar to a bunion, but without the sideways shifting of the toe. With arthritis, the toe stays straight but loses its ability to bend, especially upward. There’s often no visible bump on the inner side of the foot, though the top of the joint may feel enlarged. If your big toe is stiff but still points forward, arthritis is a stronger possibility.
Who Gets Bunions
Bunions affect roughly 1 in 5 people overall, but the numbers aren’t evenly distributed. About 24% of women develop them compared to 11% of men. They become more common with age: around 11% of people under 20 have bunions, while nearly 23% of those over 60 do. Genetics play a significant role. If your parents or grandparents had bunions, your foot structure likely predisposes you to the same pattern. Tight, narrow shoes don’t cause bunions on their own, but they accelerate the progression in feet that are already prone to them.
Signs the Bunion Is Progressing
As a bunion worsens, it creates problems beyond the bump itself. The big toe’s inward drift puts pressure on the second toe, which can develop a hammertoe: an abnormal bend in its middle joint that forces the tip downward. You may notice the second toe starting to curl or ride up over the big toe. Corns often form where the bent toe rubs against your shoe.
Increased pain during walking, difficulty finding any shoes that fit without discomfort, and numbness or burning around the bump are all signs of progression. If the big toe has shifted far enough to crowd or overlap the second toe, the bunion has moved beyond its early stages.
Getting a Definitive Answer
While bunions are often obvious enough to identify at home, an X-ray gives the full picture. Doctors measure the angle between your big toe and the long bone behind it. A normal angle is under 15 to 20 degrees. Anything beyond that confirms a bunion, and the size of the angle helps determine severity. The angle between your first and second long foot bones is also measured, with normal falling between 8 and 12 degrees. These measurements guide decisions about whether conservative care like wider shoes, padding, or toe spacers will be enough, or whether the misalignment has reached a point where surgical correction becomes worth considering.
