A new bump on the outside of your foot is easy to notice and easy to worry about. Most turn out to be minor — but they genuinely can’t be told apart reliably by feel, and a few do need treatment, so the honest answer is that only an in-person exam (sometimes with an X-ray or ultrasound) can confirm what yours is. The most common cause is a tailor’s bunion — a bony bump where the little toe meets the foot — though a soft ganglion cyst, a bone spur, or an inflamed tendon can look and feel almost the same. Below is a plain-English guide to the usual causes and, just as importantly, when a bump is worth having a podiatrist look at.
A tailor’s bunion, also called a bunionette, is a bony bump on the outside edge of the foot, right at the base of the little (fifth) toe. It is the same idea as a regular bunion, just on the opposite side of the foot: the small bone behind the little toe gradually shifts outward, the joint enlarges, and the skin over it becomes red or sore from rubbing against shoes.
Tailor’s bunions often run in families because the foot shape and mechanics that cause them can be inherited. Tight or pointed shoes do not create the deformity, but they do irritate it and can make it hurt more. If your bump is hard, sits right at the base of the little toe, and gets sore in narrow shoes, a tailor’s bunion is the likeliest explanation — and it is closely related to the more familiar big-toe kind we cover on our bunion treatment in Long Beach page.
A tailor’s bunion is the most common answer, but it is not the only one. Here are the other bumps that show up in this exact spot:
You cannot diagnose a foot bump at home, but a few features are worth noticing before your visit, because they help your podiatrist narrow things down:
| What you notice | What it often (not always) suggests |
|---|---|
| Hard, fixed, doesn’t move | A bony cause — tailor’s bunion, spur, or old fracture bump |
| Soft, squishy, moves a little, changes size | More likely a ganglion cyst or soft-tissue lump |
| Sore mainly in tight shoes | A tailor’s bunion being irritated by pressure |
| Hot, red, and suddenly very painful | Inflammation such as a gout flare — worth prompt care |
These are only clues. A cyst and a bony bump are easy to confuse by feel, so do not rely on the table to rule anything in or out — it simply gives you useful words to describe the bump when you get it checked.
See a podiatrist for any bump that is growing, painful, or simply won’t go away. Most turn out to be harmless, but a lump deserves a professional look — sooner rather than later — if any of the following apply:
A firm lump that keeps growing, or one you cannot explain, should be checked promptly — it is exactly the kind of thing a clinician should examine and, if needed, image with ultrasound or MRI, rather than watch and wait on your own. Most such lumps turn out to be harmless, but that is confirmed by an exam, not assumed.
Treatment depends entirely on what the bump turns out to be, and it almost always starts with the simplest options:
No single approach fixes every bump, and results vary from person to person. The value of a proper diagnosis is that it points you to the treatment that actually matches your problem instead of guessing.
If you have a bump on the outside of your foot that hurts, keeps growing, or you just want identified, an in-person exam is the fastest way to get a clear answer. Our board-certified podiatrists at Kim Holistic Foot & Ankle Center regularly evaluate foot bumps and can tell you what yours is and what — if anything — needs to be done. You can meet our doctors or request a visit whenever you’re ready.
See a podiatrist for any bump that grows, hurts, or won’t go away. Most turn out benign — usually a tailor’s bunion or a ganglion cyst — but only an exam, sometimes with imaging, can confirm what it is and rule out anything that needs treatment.
A tailor’s bunion (bunionette) is a bony bump on the outside of the foot at the base of the little toe. It forms as the bone behind the fifth toe gradually shifts outward and the joint enlarges, and it is closely related to the more common big-toe bunion.
Have any bump that is growing or painful checked by a podiatrist rather than waiting it out. A ganglion cyst may change size on its own, but a bony bump such as a tailor’s bunion or bone spur will not disappear without treatment.
You often can’t tell reliably on your own — cysts and bony bumps are easily confused by feel. A podiatrist can distinguish them with an exam and, when needed, an X-ray or ultrasound. As a rough guide only, cysts tend to feel soft and movable while bony bumps feel hard and fixed.
Usually not. Most bumps are managed with roomier shoes, padding, orthotics, or draining a cyst. Surgery is considered only when a painful bump does not improve with conservative care, so it is the exception rather than the first step.
