That Bump on the Side of Your Big Toe — What It Is and What to Do About It

A bunion is one of the most common foot problems we see, and one of the most misunderstood. Most people think of it as a growth or a calcium deposit on the side of the foot. It is neither. A bunion is a structural deformity — the big toe drifts toward the second toe, the first metatarsal bone shifts outward in the opposite direction, and the resulting misalignment creates the bump at the base of the big toe. The bump is bone that was already there, now protruding because the joint has shifted out of its normal position.

This distinction matters for treatment. Because a bunion is a structural problem, it does not get better with massage, splints, spacers, or exercises. Conservative treatment manages the symptoms and slows progression — surgery is the only way to actually correct the deformity. The goal of a thorough evaluation is to determine which approach is right for your situation. Our podiatrists evaluate and treat bunions at our Coon Rapids and Golden Valley offices, serving patients across the north and west metro including Maple Grove, Champlin, Blaine, Plymouth, Wayzata, Minnetonka, and Edina.

Not all bunions need surgery, and not all bunions need to be treated at all — but all bunions are progressive. A bunion that is not causing significant pain today will cause more significant pain in the future if the underlying mechanics are not managed. Getting an evaluation now, before the deformity advances, gives you the most options.

What Is a Bunion?

The medical term is hallux valgus — hallux meaning big toe, valgus meaning angled outward. As the big toe drifts toward the second toe, the first metatarsal bone moves in the opposite direction, creating a widened forefoot and the characteristic prominence at the metatarsophalangeal (MTP) joint. Over time, the joint capsule stretches, the tendons pull at abnormal angles, and the joint itself can develop arthritic changes that make the deformity progressively more painful and harder to correct.

Bunions are a progressive condition. They do not resolve on their own, and the rate of progression varies significantly between patients. Some bunions remain relatively stable for years; others advance quickly, particularly when aggravated by unsupportive or narrow footwear. Periodic evaluation with weight-bearing X-rays allows us to track whether the deformity is stable or advancing.

Bunions are primarily hereditary — not caused by shoes. The underlying foot type that predisposes someone to hallux valgus is genetic. Narrow shoes and high heels do not cause the deformity, but they can accelerate progression and bring on symptoms earlier. This is why women are more likely to be symptomatic, even though bunions are nearly as common in men.

Causes & Risk Factors

• Inherited foot structure: the single largest risk factor. Low arches, flexible joints, and certain foot types that allow the first metatarsal to drift outward are strongly heritable. If a parent has a bunion, the probability of developing one is significantly higher.
• Footwear: narrow toe boxes, pointed toes, and high heels compress the forefoot and accelerate progression in feet that are already predisposed. Footwear does not initiate the deformity but can significantly worsen it.
• Inflammatory arthritis: rheumatoid arthritis and other inflammatory conditions can drive rapid bunion progression through joint destruction and altered mechanics.
• Hypermobility: excessive mobility at the first MTP or first tarsometatarsal joint increases the tendency of the first metatarsal to drift.

Symptoms

Bunion symptoms range from none at all (in early deformity) to severe daily pain. Common presentations:

• A visible bony prominence at the base of the big toe on the inner side of the foot
• Pain, soreness, or aching at the bunion site — worsened by shoes that press on the bump
• Redness, swelling, or warmth at the joint from bursitis — inflammation of the fluid-filled sac over the bump
• A burning sensation or occasional numbness from pressure on the digital nerve
• Difficulty finding shoes that fit comfortably, particularly with dress or work footwear
• Pain with prolonged standing or walking, particularly at the end of the day
• Secondary hammertoe: as the big toe drifts toward the second toe, the second toe is pushed upward and can develop a hammertoe deformity — a common and important concurrent condition to evaluate.

Diagnosis

Diagnosis is straightforward on examination, but we also take weight-bearing X-rays to measure the degree of deformity and assess the joint. The two key measurements are the hallux abductus angle (the angle between the big toe and first metatarsal) and the intermetatarsal angle (the angle between the first and second metatarsals). These measurements determine the severity of the deformity and guide surgical planning if correction is indicated.

We also assess the joint itself for arthritic change, the flexibility of the deformity (whether it can be passively corrected), and the overall alignment of the foot. These factors collectively determine the most appropriate surgical procedure if that path is chosen.

Treatment at Family Foot & Ankle Clinic

Treatment depends on the severity of the deformity, the degree of symptoms, and the patient’s activity level and goals. The important framing: conservative care is not a failure to treat — it is the appropriate first step for many patients. Surgery is not a last resort — it is the right choice for patients whose pain and functional limitation are not adequately managed conservatively.

Conservative Management — Symptom Control and Progression Slowing

Footwear modification. The most impactful immediate intervention. Shoes with a wide, deep toe box that do not press on the bunion significantly reduce pain. Avoiding pointed toes, narrow dress shoes, and heels above 1–2 inches reduces the daily compression on the deformity. Our Shoe Recommendations Guide has specific current picks.

Padding and protective devices. Bunion shields and pads placed over the prominence reduce direct shoe pressure and friction. Toe spacers (placed between the big and second toe) can improve comfort. These are available through our office or at MyFootShop.com. They manage symptoms but do not correct the deformity.

Custom orthotics. For patients with underlying biomechanical drivers — overpronation, hypermobile first ray, or arch insufficiency — a custom orthotic can slow progression by improving first metatarsal stability and reducing the forces that drive the drift. More on our Custom Orthotics page.

Anti-inflammatories and icing. NSAIDs and ice (15 minutes, several times per day) reduce acute bursitis flares. Useful for symptomatic management during periods of increased activity or after prolonged standing.

Injection therapy. A corticosteroid injection into the bunion bursa can reduce acute inflammation and provide significant short-term relief during a flare. Used selectively rather than routinely, and not as a substitute for addressing the underlying deformity.

Conservative care does not correct a bunion. A bunion splint worn at night will not straighten the deformity. A toe spacer will not reverse the joint misalignment. These are symptom management tools — valuable for many patients, but it is important to have accurate expectations. If you have been using conservative measures and are still in significant pain, the conversation about surgery is worth having.

Surgical Correction — Bunionectomy

Surgery is recommended when conservative treatment no longer adequately controls pain and when the deformity is limiting daily activities or footwear choices. Bunion surgery (bunionectomy) is not simply removing the bump — it corrects the underlying bony misalignment, restores the joint to a more normal position, and addresses any associated soft tissue imbalance.

The specific procedure depends on the severity of the deformity, the joint health, the patient’s age, and activity level. Options range from:

• Osteotomy procedures: the most common approach. A cut is made in the first metatarsal bone and it is repositioned and held with hardware (screws or plates). The Lapiplasty and Scarf osteotomy are modern variations with favorable outcomes.
• Lapidus fusion: for patients with significant hypermobility at the first tarsometatarsal joint, fusion of that joint corrects the deformity at its root cause rather than at the metatarsal level alone.
• Distal soft tissue procedures: release of the tight lateral capsule and rebalancing of the tendons alongside the bony correction.

Recovery depends on the specific procedure. Most patients are weight-bearing in a surgical boot within days to weeks, with return to regular shoes at 6–8 weeks and full activity at 3–6 months. Weight-bearing X-rays during healing confirm the correction is maintaining its position.

Frequently Asked Questions

Will my bunion go away without surgery?

No. Bunions are a structural deformity and do not resolve without surgical correction. Conservative treatment manages pain and may slow progression, but it does not straighten the toe or reposition the joint. If your bunion is not currently causing significant pain, conservative management is entirely appropriate — but do not expect the deformity to improve.

Is bunion surgery worth it?

For patients with significant pain, difficulty with footwear, or functional limitation that is not adequately managed conservatively, the answer is usually yes. Modern bunion surgery has excellent outcomes, predictable recovery, and high patient satisfaction rates. The decision involves weighing your current quality of life against the recovery period — typically 6–8 weeks in a boot and 3–6 months to full activity. We will help you think through that trade-off at your visit.

Can I wait and see how my bunion progresses?

Yes, with appropriate monitoring. Periodic weight-bearing X-rays every 1–2 years allow us to track whether the deformity is stable or advancing. A bunion that is stable and minimally symptomatic can be monitored without intervention. The caution is that delaying surgery until the deformity is very advanced may require a more complex procedure and longer recovery. Earlier surgical correction while the joint is still healthy often produces better outcomes than waiting until arthritis has set in.

I’ve been told I have a bunion on the outside of my foot too. Is that different?

Yes — that is a tailor’s bunion, or bunionette, a similar deformity at the fifth metatarsal head on the outer side of the foot. It is treated on the same principles as a hallux valgus bunion but involves different anatomy and sometimes different surgical approaches. See our Tailor’s Bunion page.
