A healthcare professional can often identify a bunion from the history and a physical examination of the foot. They assess the big toe while you stand, joint motion, tenderness, skin changes, footwear problems and walking. Weight-bearing X-rays may be used to measure alignment, look for arthritis and plan surgery when appropriate.
What questions might you be asked?
Expect questions about when the bump or toe drift appeared, where pain occurs, which shoes or activities aggravate it, and whether symptoms limit walking. Prior injury, inflammatory arthritis, diabetes and circulation or sensation problems are also relevant.
What happens during the examination?
The clinician may inspect both feet while seated and standing, feel the joint, assess big-toe motion and observe related calluses or lesser-toe changes. They may also examine gait and shoe fit.
Are X-rays always required?
No. A straightforward, painless bunion may not need imaging. Weight-bearing X-rays become more useful when symptoms are significant, the diagnosis is uncertain, arthritis is suspected or an operation is being planned.
What conditions can look similar?
Gout, hallux rigidus, arthritis, injury, infection and soft-tissue lumps can cause symptoms near the big-toe joint. Sudden hot swelling is a different pattern from the gradual toe drift typical of hallux valgus.

How does diagnosis guide treatment?
Assessment connects the visible alignment with the actual source of symptoms. That helps distinguish a footwear-pressure problem from joint arthritis or another condition and prevents a product from being used as a substitute for diagnosis.

The history narrows the problem before imaging
Gradual toe drift with shoe pressure is a different story from an overnight episode of severe heat and swelling. A clinician will ask whether pain is over the bump, inside the joint or under the forefoot; whether the toe is stiff; and whether symptoms occur only in certain shoes. Medical history matters because inflammatory arthritis, nerve problems, diabetes and prior injury can change the differential diagnosis and care plan.
Why the examination is often weight-bearing
Foot alignment changes under load. Looking at both feet while standing can reveal toe drift, arch behavior, lesser-toe crowding and callus patterns that may be less obvious when seated. Joint motion and tenderness are then assessed directly. Gait observation can show whether pain is changing push-off or stride.
What weight-bearing X-rays add
AAOS notes that standing X-rays show bone alignment and can identify associated MTP-joint damage or arthritis. Clinicians may measure the hallux valgus and intermetatarsal angles, but measurements are interpreted with symptoms and examination findings rather than used as a treatment decision by themselves.
When other tests may be needed
Bunions do not usually require advanced imaging. Blood tests, joint-fluid analysis, ultrasound or other studies may be considered when gout, infection, inflammatory arthritis, a mass or another diagnosis is suspected. The test should answer a clinical question rather than confirm a bump that is already obvious.
What the assessment should clarify
A useful diagnosis goes beyond naming hallux valgus. It should clarify whether symptoms come mainly from skin pressure, the MTP joint, transfer load beneath the forefoot or an overlapping second-toe problem. It should also identify arthritis, vascular or neurological concerns that change which self-care options are safe.
Can a photo or online quiz diagnose a bunion?
A clear photograph may show a typical alignment pattern, but it cannot test joint motion, sensation, circulation or tenderness and does not reproduce weight-bearing radiographic information. Online tools can organize questions; they cannot rule out gout, infection, fracture or arthritis when symptoms are atypical.
What to expect after diagnosis
A painless bunion may simply be observed. When symptoms matter, the plan may begin with footwear and pressure reduction, then add a targeted device, therapy or orthosis if there is a defined goal. Referral for surgery is usually considered when pain or functional limitation remains substantial despite appropriate conservative measures.
