Bunion Symptoms: Big Toe and Little Toe

A bunion is a bony bump at the big toe joint, and the AAOS describes the symptom set as pain and tenderness, redness and inflammation, hardened skin on the bottom of the foot, a callus or corn over the bump, and stiffness with limited motion of the big toe. The bump is the visible part. The drift underneath it is the actual condition.

The bump is the last thing to appear

Hallux valgus is progressive, and it works from the inside out. The AAOS describes the long metatarsal bone shifting toward the inside of the foot while the phalanx bones of the big toe angle toward the second toe. Only once that has gone far enough does the head of the metatarsal push against the skin and become the lump people recognize. The APMA frames the cause as years of abnormal motion and pressure over the MTP joint — the way you walk and the foot type you inherited, meeting the shoe you chose.

Signs on the big toe

• A prominence on the inner edge of the foot at the base of the big toe
• The big toe angling toward the second one, mild at first
• Redness, swelling or pain at or near the joint, in the APMA’s list
• Restricted or painful motion of the big toe
• Hardened skin under the ball of the foot, from the load shifting sideways
• A callus or corn sitting directly on the bump where the shoe presses

Signs on the little toe

The mirror image has its own name: a bunionette, or tailor’s bunion. StatPearls describes a lateral bony protrusion along the fifth metatarsal head, with painful callosities over it and a forefoot that measures wider than it used to. Estimated prevalence is 13.8%, and 61.2% of those affected report a positive family history — a heredity signal as strong as the big toe version. It travels with flat feet and with hallux valgus, so a foot often has both ends going at once.

What it does to the neighboring toes

A big toe pressing sideways has to displace something. The AAOS lists hammer toe deformity in the second toe, forced out of alignment by the pressure, and corns and calluses forming where toes are pushed into rubbing against each other — which is how a corn between toes shows up on a foot that never used to get them. Bursitis over the prominence and arthritis from damaged articular cartilage complete the list.

Signs the joint itself is involved

Stiffness and restricted big toe motion are the ones that change the conversation. A bump that hurts only in tight shoes is a pressure problem. A joint that has lost range, aches without a shoe on, and grinds when you bend the toe suggests the cartilage inside is affected — the AAOS names arthritis among bunion complications for that reason. See bunion pain causes for how to tell those apart, and corns and bunions on feet for the wider comparison with skin lesions.

When to see a podiatrist

The APMA’s answer is direct: if you think you have a bunion, see a podiatrist, because bunions tend to get larger and more painful if left untreated. Go sooner if walking is affected, if ordinary shoes no longer fit, or if you have diabetes, since the hardened skin over a prominence is exactly where a foot ulcer starts.
