A bunion shows up as a bony bump at the base of your big toe, on the inner side of your foot. You can usually both see and feel it. If your big toe is angling inward toward your other toes and a hard, protruding knob has formed at that joint, you’re almost certainly looking at a bunion.
What a Bunion Looks Like
The hallmark sign is a visible bony growth right where your big toe meets your foot. Stand barefoot on a flat surface and look down at your feet. In a foot without a bunion, the big toe points roughly straight ahead. With a bunion, the big toe leans noticeably toward the second toe, and the joint at the base of the big toe juts outward, creating that characteristic bump on the inner edge of your foot.
The bump itself is hard because it’s bone, not a fluid-filled sac or soft tissue swelling. In early stages it may be subtle, just a slight widening of the foot near the big toe. Over time it becomes more prominent. The skin over the bump often looks red or discolored and may feel warm to the touch, especially after a long day on your feet or after wearing tight shoes. You might also notice thickened, rough skin (corns or calluses) forming over the bump or between toes that are now pressing against each other.
How a Bunion Feels
Not all bunions hurt, which is why some people aren’t sure whether what they’re seeing is actually one. Pain, when it does show up, tends to concentrate right at the bump and gets worse with pressure. Shoes that are narrow or pointed squeeze the bunion and intensify the soreness. Walking or standing for extended periods can produce a deep, aching pain at the joint. Some people describe a burning sensation when they try to bend the big toe.
Stiffness is another common sign. If you sit down and try to move your big toe up and down, a bunion often limits how far it can go. The joint may feel tight or locked, and that restricted motion can change the way you walk without you even realizing it. Over time, you may also notice numbness in or around the big toe as the shifted bone puts pressure on nearby nerves.
A Simple Home Check
You can do a quick self-assessment with bare feet and a flat surface. Stand naturally with your weight evenly distributed and look at the alignment of your big toes. Draw an imaginary line from the center of your heel through the base of your big toe. If your big toe deviates away from that line, angling toward your second toe, that’s the misalignment behind a bunion. Now run your finger along the inner edge of the joint. If you feel a firm, bony ridge that doesn’t exist on a foot without a bunion, that confirms what you’re seeing.
Compare both feet. Bunions can develop on one foot or both, and they’re often more advanced on one side. Also check whether your shoes are wearing unevenly or whether you’ve been unconsciously buying wider shoes over the past year or two. These are practical clues that your foot shape has been changing.
Bunions on the Pinky Toe Side
Bunions don’t only form at the big toe. A tailor’s bunion (sometimes called a bunionette) appears as a bony bump on the outside of your foot at the base of your pinky toe. The signs mirror a standard bunion: the little toe angles inward toward the other toes, a hard bump forms on the outer edge of the joint, and you feel pressure or pain when shoes press against it. Redness, swelling, and calluses on the pinky toe are common. If you’re noticing discomfort on the outer edge of your foot rather than the inner side, this is likely what you’re dealing with.
Conditions That Look Similar
A few other problems can cause pain and swelling in the same area, so it helps to know the differences.
Gout often strikes the big toe joint and can look like a bunion flare at first glance. The key difference is speed and severity. A gout attack comes on suddenly, often overnight, with intense, throbbing pain and dramatic swelling. The joint turns red or purplish and feels hot. A bunion develops gradually over months or years and doesn’t produce that kind of acute, overnight crisis.
Arthritis in the big toe joint (sometimes called hallux rigidus) also causes stiffness and pain in the same spot. But arthritis typically makes the joint stiff in all directions without the sideways deviation of the toe. If your big toe hurts and won’t bend but points straight ahead without a visible bump pushing outward, arthritis is more likely than a bunion. That said, both conditions can coexist.
A fluid-filled sac called a bursa can become inflamed right over the bunion joint, adding soft, puffy swelling on top of the hard bump. If the area feels squishy rather than purely bony, bursitis may be layered on top of an underlying bunion.
Signs a Bunion Is Getting Worse
Bunions are progressive. They don’t reverse on their own, and without changes to footwear or other interventions, they tend to worsen over time. There are a few signals that yours is advancing beyond a cosmetic issue:
- Hammertoe development. When the big toe crowds its neighbor, the second toe can buckle upward at its middle joint, forming a painful bend called a hammertoe. If the toe next to your big toe is starting to curl or claw, the bunion is affecting your foot’s overall mechanics.
- Ball-of-foot pain. As the bunion shifts weight away from the big toe, the smaller bones in the ball of your foot absorb extra force. Aching or swelling under the ball of the foot (called metatarsalgia) is a sign that pressure distribution has changed.
- Bursitis over the bump. Repeated friction from shoes can inflame the fluid-filled cushion over the joint, adding a layer of soft, tender swelling on top of the bony bump.
- Daily activity limits. If the pain is keeping you from walking comfortably, exercising, or wearing most shoes, the bunion has moved past the mild stage. Surgery is generally recommended only when a bunion causes frequent pain or limits daily activities.
What Happens at a Medical Evaluation
Most bunions can be identified visually, but a podiatrist or orthopedic specialist will typically order an X-ray to measure the exact angle of deviation. A normal big toe joint sits at an angle of roughly 15 degrees or less relative to the first long bone of the foot. Once that angle exceeds about 20 degrees, the bunion is clinically significant. The doctor will also measure the angle between the first and second long bones of the foot, which is normally between 8 and 12 degrees. A wider angle here means the bone itself has shifted, not just the toe.
These measurements matter because they determine whether the bunion is mild, moderate, or severe, and that classification shapes which treatments make sense. Mild bunions often respond well to wider shoes, padding, and toe-spacing devices. Moderate to severe bunions with progressive pain may eventually need surgical correction to realign the bone.
Quick Self-Check Summary
If you’re still unsure, run through these questions:
- Is there a hard, bony bump on the inner side of your foot at the big toe joint? This is the defining feature.
- Does your big toe lean toward your second toe? Even a slight inward angle counts.
- Is the area red, swollen, or tender, especially in shoes? Inflammation at the bump is a strong indicator.
- Has your big toe become stiffer over time? Reduced range of motion at that joint points to bunion-related changes.
- Have your shoes started feeling tighter on one side? A widening forefoot is one of the earliest practical signs.
If you answered yes to two or more of these, a bunion is the most likely explanation. An X-ray can confirm it and tell you how far it’s progressed.
