What Is a Bunion?

For most people, a bunion announces itself in a shoe shop, not a doctor's office. A pair that fitted last year suddenly rubs on one spot — the bump at the base of your big toe — and by the end of the day that spot is sore and a little red. The short video at the top of this page, "Formation of Bunions", runs just 1 minute 20 seconds and shows how bunions appear: what is happening at that joint while the bump you can feel is quietly taking shape. Here's what to expect from the condition itself, from that first rubbing shoe onwards.

The bump is a joint that has drifted, not a growth

Despite how it feels, a bunion isn't a lump growing on the bone. It's the big-toe joint moving out of line. The long bone behind the toe — the first metatarsal — tips inward toward the other foot, while the big toe itself leans the other way, toward the second toe. The "bump" is simply the end of that metatarsal bone becoming prominent where the joint has angled. Clinicians call the pattern hallux valgus. It tends to develop slowly, over years. Why one person's joint drifts and another's doesn't isn't fully settled; it often runs in families, and tight or narrow shoes can aggravate a joint that is already drifting, even if they didn't start the process. Over time the leaning toe can crowd its neighbour, and the skin over the bump may thicken or become tender from friction.

At the appointment: what the clinician actually does

Expect the examination to be mostly about alignment and shoes. The clinician will look at the foot while you're standing, because the drift shows most clearly under your own body weight, and will gently move the big toe to feel how stiff the joint has become. They'll ask which shoes hurt, where exactly the pain sits, and whether the second toe is being pushed around. A standing X-ray is often taken — not because the diagnosis is in doubt, but because it lets the clinician measure the angles between the bones, and those measurements are what later decisions rest on. If you're weighing up foot pain more generally, our guide to plantar fasciitis covers the heel-and-arch pattern that is often confused with forefoot problems like this one.

Everyday care comes first — and for many people it's enough

Here's the reassuring part: a visible bump is not, by itself, a reason for an operation. Care usually starts with the shoe, not the scalpel. A wider toe box gives the joint room instead of squeezing it; soft uppers rub less than stiff leather; and padding over the bump can settle the sore, red patch that friction causes. Many people find that once the pressure comes off, the pain largely does too — the bump remains, but it stops dominating the day. What everyday care can't do is push the joint back into line: no shoe, splint, or spacer permanently re-straightens an established bunion, and it's worth being sceptical of products that promise otherwise.

If surgery enters the conversation, this is what it involves

Surgery — a bunionectomy — is generally discussed when pain persists despite sensible shoes, when walking is being limited, or when the drifting toe is damaging its neighbour. The aim is to realign the joint: the surgeon repositions the metatarsal bone and the toe, sometimes removing the prominent excess of bone, and holds the correction while it heals. If you'd like to see what that looks like in practice, the longer recording "Bunion Surgery: Relief from Foot Pain" follows a podiatrist performing a bunionectomy to get a patient back on her feet and back to work. Recovery typically means a period in a protective shoe or boot with weight-bearing built up gradually, and the exact plan varies with the procedure chosen — your surgeon will map it out against your X-ray measurements. One honest point to raise at that visit: bunions can occasionally come back over time, particularly if the underlying drift was severe, so it's a fair question to ask about.

Frequently Asked Questions

Do bunions always need surgery?

No. Many bunions are managed for years with wider, softer shoes and simple padding, and surgery is usually considered only when pain persists despite those changes or walking becomes limited.

Can a bunion go away on its own?

The bump won't disappear, because it reflects the position of the bones at the joint — but the soreness around it often settles once pressure and friction from footwear are reduced.

When should I have a bump on my foot checked?

Book a check if the area is regularly painful, if shoes no longer fit comfortably, if the big toe is starting to push into or over the second toe, or if the skin over the bump keeps breaking down. New foot pain with redness and swelling that comes on suddenly is also worth prompt attention, as it can have other causes.
