Understanding Bunions

Top view of foot with bones ghosted in, showing bunion.A bunion is a bony bump on the joint at the base of the big toe. A bunion changes the shape of the foot. It can also cause pain and problems using the foot.

A person with a bunion will have a bony bump at the base of the big toe. This is caused by misalignment of the toe joint, causing the bones to sit at an angle instead of straight. The big toe often turns in toward the second toe. In time, the big toe may start to overlap the second toe.  

What causes bunions?

It is not clear what causes bunions, but many factors are likely involved. Bunions often run in families. They may be more common in people who have loose joints. Wearing tight shoes may also cause bunions.

Symptoms of bunions

At first, the problem may be painless. As symptoms develop, they may include:

  • Foot pain or stiffness

  • Swelling over the joint

  • Skin irritation or thickened skin over the joint

Treatment for bunions

In most cases, your healthcare provider will try nonsurgical treatments first. Most of these treatments won’t cure the bunion, but they can help relieve symptoms and keep the bunion from getting worse. These include:

  • Wearing low-heeled shoes with a wide toe box. This can help relieve pressure on the bunion and make walking more comfortable.

  • Using padding or special shoe inserts called orthotics. Inserts can be custom-made for your foot. They help support the foot and may change how the foot is aligned.

  • Wearing a toe splint at night. This can help hold the toe in a straighter position.

  • Putting an ice pack on a swollen joint. This can help reduce pain and swelling.

If the bunion causes severe pain or problems using the foot, your provider may recommend surgery. During surgery, excess bone may be removed and the joint is realigned.

 

When to call your healthcare provider

Call your healthcare provider right away if you have any of these:

  • Fever of 100.4°F (38°C) or higher, or as directed

  • Symptoms that don’t get better, or get worse

  • New symptoms
