Overview
Hallux valgus, commonly called a bunion, is a progressive foot condition in which the big toe gradually angles toward the other toes. This deformity changes the alignment of the first metatarsal and can create a bony bump over the inside of the foot. When the joint is irritated or does not move smoothly, it can lead to pain, swelling, stiffness, and difficulty finding comfortable shoes. In some people, the surrounding soft tissues become inflamed and the bunion area can become tender with walking.
Symptoms
Patients often notice a visible bump on the inside of the forefoot at the base of the big toe. Pain and aching are commonly worse with tight or narrow footwear and with prolonged standing or walking. You may also notice swelling or redness around the bunion, stiffness in the big toe joint, and pressure under the forefoot. Over time, the big toe may drift more toward the lesser toes, which can make everyday activities and shoe wear harder.
Causes
Hallux valgus develops when the first metatarsophalangeal (MTP) joint becomes unstable and the big toe drifts inward, often due to gradual biomechanical imbalance over time. Abnormal foot mechanics, foot shape, and joint laxity can overload the joint and soft tissues, leading to inflammation and progressive deformity. Arthritis may also develop in the bunion joint, which can worsen pain and stiffness.
Risk Factors
Risk is higher in people with a family history of bunions and in those with certain foot shapes and hypermobility. Wearing narrow, tight, or high-heeled shoes can increase pressure at the forefoot and accelerate irritation of the bunion area. Long periods of standing or activities that overload the forefoot may worsen symptoms, and having existing foot or toe deformities can contribute to abnormal alignment.
Prevention
You can reduce irritation by choosing wide, supportive shoes with a roomy toe box and avoiding prolonged high-heel or narrow footwear. Using custom or off-the-shelf supports when appropriate can help improve foot alignment and reduce pressure on the bunion. Maintaining healthy body weight, staying strong in the foot and lower leg, and using regular mobility and stretching can help minimize flare-ups and slow functional decline.
How the Diagnosis Is Evaluated
Clinicians typically start with a history of pain, shoe tolerance, swelling, and how the deformity has changed over time. A physical exam focuses on alignment of the big toe, tenderness over the bunion and MTP joint, range of motion, and how the foot loads during walking. Weight-bearing foot X-rays are often used to confirm the diagnosis and measure the degree of deformity; additional imaging is usually not needed unless symptoms suggest another problem.
Nonsurgical Treatment Options
Conservative care aims to reduce pain, protect the joint, and improve function without changing the deformity immediately. Shoe modification is often the most helpful step, including wide toe-box footwear, cushioning insoles, and, when needed, orthotics to redistribute pressure under the forefoot. Bunions may also feel better with toe spacers, bunion pads, or braces designed to reduce friction and support the toe position. Anti-inflammatory or pain-relieving medications, such as NSAIDs when safe for you, can help control flare-ups. Physical therapy can improve mobility and strengthen the muscles that support toe alignment, while limiting aggravating activities can reduce recurrent symptoms. If the MTP joint or adjacent bursa is significantly inflamed, a clinician may consider a corticosteroid injection to calm pain and swelling, usually as part of a broader conservative plan.
When to Seek Medical Attention
Seek prompt medical attention if you have rapidly worsening swelling, significant redness or warmth, fever, or drainage, because these can suggest infection or severe inflammation. Get evaluated urgently if you cannot bear weight, have severe or escalating pain despite rest, or notice numbness, burning pain, or progressive weakness in the foot. If the bunion deformity is progressing quickly or you are developing worsening pressure sores or skin breakdown, you should be assessed soon to prevent complications.
Frequently Asked Questions
Yes, bunions often progress over time as toe alignment shifts and the joint becomes more irritated or stiff.
Many people manage symptoms successfully with proper footwear, padding, and orthotics, especially when arthritis has not advanced significantly.
Next Steps
If you have bunion pain that limits shoes or walking, start by scheduling an evaluation with a foot and ankle clinician for a focused exam and, when appropriate, weight-bearing X-rays. In the meantime, switch to wide supportive footwear and consider cushioning or orthotic support to reduce pressure while you monitor symptoms.
