Bunions: Causes, Symptoms, and How Physiotherapy Can Help

Reviewed by the Physiotherapy Team at Waterloo Sports Medicine Centre 

Do you have a painful bump on the side of your big toe? You may have a bunion, also known as hallux valgus. Bunions are a common foot condition that can make walking, exercising, and wearing certain shoes uncomfortable. Fortunately, early treatment and proper management can help reduce pain and slow progression. 

What Is a Bunion? 

A bunion is a bony prominence that develops at the base of the big toe joint. It occurs when the big toe gradually shifts toward the second toe, causing the joint to become misaligned. Over time, the deformity may worsen and lead to pain, swelling, stiffness, and difficulty fitting into shoes. 

What Causes Bunions? 

There is no single cause of bunions. Instead, they typically develop due to a combination of factors, including: 

• Genetics and inherited foot structure 

• Flat feet or excessive foot pronation 

• Joint instability or ligament laxity 

• Arthritis, particularly rheumatoid arthritis 

• Repetitive stress on the feet 

• Wearing narrow or tight-fitting footwear that places pressure on the toes

Who Is at Risk? 

You may be at a higher risk of developing bunions if you: 

• Have a family history of bunions 

• Are female, as bunions are more common in women 

• Have flat feet or altered foot mechanics 

• Spend long periods standing or walking 

• Have inflammatory conditions such as rheumatoid arthritis

  
  

Common Symptoms 

Bunion symptoms can include: 

• A visible bump on the side of the big toe joint 

• Pain or tenderness around the joint 

• Redness and swelling 

• Stiffness and reduced movement of the big toe 

• Corns or calluses between the first and second toes 

• Difficulty wearing certain shoes or participating in activities 

  
  

How Can Physiotherapy Help? 

While physiotherapy cannot reverse the bony deformity, it can significantly improve symptoms, reduce pain, and help you stay active. 

Treatment may include: 

• Education on footwear modifications 

• Stretching and strengthening exercises for the foot and ankle 

• Exercises to improve toe mobility and foot alignment 

• Manual therapy to improve joint mobility 

• Taping techniques to support the big toe 

• Gait assessment and walking retraining 

• Activity modifications to reduce stress on the joint  

At Waterloo Sports Medicine Centre, our physiotherapists can also work closely with our pedorthic services to determine whether custom foot orthotics may help improve foot mechanics and reduce pressure on the affected joint. 

Recovery and Healing Timeline 

Bunions generally do not heal on their own, and the deformity may gradually progress over time. However, conservative treatment can often successfully manage symptoms and improve function.  Many people notice improvement in pain and walking tolerance within 6 to 12 weeks of beginning physiotherapy and footwear modifications. The timeline depends on the severity of the bunion and how consistently treatment recommendations are followed.

For severe or persistent cases, surgery may be considered. Recovery after bunion surgery typically takes 6 to 12 weeks for basic activities, while complete recovery and return to higher-impact activities may take 3 to 6 months or longer depending on the procedure performed.

\When Should You Seek Treatment? 

You should consider seeing a healthcare professional if you have: 

• Persistent foot pain 

• Difficulty walking or exercising 

• Trouble finding comfortable footwear 

• Progressive changes in the position of your big toe
