If you’ve noticed a painful lump on your foot, you might be wondering: is this a bunion or a corn? While both can cause discomfort and both show up around the toes, they’re actually very different conditions and the treatment for each is completely different too.

What Is a Bunion?
A bunion (medically called hallux valgus) is a structural deformity of the foot — specifically, a deviation of the big toe joint. When the big toe drifts inward toward the other toes, the joint at the base pushes outward, creating that characteristic bony bump on the inside of the foot.
Key things to know about bunions:
- They’re a joint problem, not just a skin problem
- They’re almost always found at the base of the big toe
- A bony callus often develops on the side of the toe from pressure
- Some people also develop a tailor’s bunion (or bunionette) on the outside of the foot, at the base of the little toe
- They’re progressive — meaning they tend to worsen over time if left untreated
What Is a Corn?
A corn is a concentrated build-up of dead skin cells that forms a hard, centralised mass. Unlike bunions, corns aren’t a structural issue — they’re a skin response to repeated friction or pressure.
Key things to know about corns:
- They can appear anywhere on the foot — between toes, on the soles, even on top of the toes
- They often feel like a small stone under the skin
- They’re entirely made of dead tissue, which is why removing them is usually painless
- Treatment is quick — most corns can be debrided (professionally removed) in just a few minutes
So How Do You Tell Them Apart?
Here’s a simple way to think about it:
A bunion is a bone problem. A corn is a skin problem.
If you have a bony protrusion at the base of your big toe that feels hard and doesn’t move, that’s likely a bunion. If you have a tight, concentrated circle of hard skin that can develop anywhere on your foot, that’s more likely a corn.
That said — you can have both at the same time. A bunion creates abnormal pressure points that can trigger corn formation over the bony area. So what looks like “just a corn” on the side of your big toe might actually be a corn developing over a bunion.
Why Does the Difference Matter?
Because the treatment paths are completely different.
Corns can usually be resolved quickly. A podiatrist can debride the corn in a single appointment — often in just a few minutes — and then help you address the underlying cause (whether that’s footwear, gait, or pressure patterns).
Bunions are a longer-term management challenge. They don’t go away on their own, and if left too long without proper assessment and management, surgical intervention may eventually be needed. Early intervention with orthotics, footwear advice, toe spacers, and exercises can significantly slow progression and reduce pain.
When Should You See a Podiatrist?
You should book in with a podiatrist if:
- You have a painful bump on your foot that’s been there for a while
- You’re not sure whether you’re dealing with a bunion or a corn
- You’ve been treating a corn and it keeps coming back
- Your big toe appears to be drifting toward your other toes
- You’re finding it hard to fit into regular footwear
Don’t wait until the pain is severe. The earlier a bunion is assessed, the more options you have for non-surgical bunion treatment.
