What Is a Bunion?

A bunion is a bony bump that forms at the base of the big toe where it meets the foot. It develops when the bones in the front part of your foot shift out of place — forcing the tip of the big toe to angle toward the smaller toes and causing the joint at the base of the big toe to stick out.

Bunions can be painful and progressive. Left untreated, they tend to worsen over time, making walking and wearing shoes increasingly difficult.

What Causes Bunions?

  • Genetics and inherited foot structure
  • Abnormal foot mechanics or flat feet
  • Tight, narrow, or high-heeled footwear
  • Inflammatory arthritis (such as rheumatoid arthritis)
  • Injury or repetitive stress on the joint

Symptoms

  • A visible bump on the outside of the big toe joint
  • Pain or soreness around the joint — especially with activity
  • Redness, swelling, or inflammation
  • Big toe stiffness or limited range of motion
  • Difficulty fitting into shoes comfortably
  • Corns or calluses from the big toe rubbing against neighboring toes

How We Diagnose and Treat Bunions

We evaluate your bunion with a physical exam and, when needed, X-rays to assess the degree of joint misalignment. Treatment is personalized to the severity of your condition and your activity level.

Conservative (Nonsurgical) Treatment

For mild to moderate bunions, nonsurgical approaches can relieve pain and slow progression:

  • Custom orthotics and shoe inserts to redistribute pressure
  • Padding or taping to reduce friction and relieve pressure
  • Anti-inflammatory medications to reduce swelling
  • Ice therapy for acute pain and inflammation
  • Footwear modifications — wider toe boxes, lower heels, softer materials
  • Splinting or night braces in select cases

Bunion Surgery (Bunionectomy)

When conservative treatments no longer control your pain and the bunion is interfering with your daily activities, surgical correction may be the best option. A bunionectomy involves realigning the bones, removing the bony bump, and correcting the underlying structural imbalance.

Our surgeons discuss all options thoroughly with patients before recommending surgery, and recovery plans are individualized to help you return to full activity as smoothly as possible.

Related Conditions

Bunions often occur alongside other forefoot problems. If you have a bunion, you may also experience hammertoes — a common companion deformity caused by the same toe misalignment. Chronic bunion pressure can also contribute to heel and arch pain as your gait shifts to compensate. Our podiatrists will assess your entire foot during your evaluation.

Don't Let Bunions Hold You Back

Whether you're looking for conservative relief or considering surgery, the team at Big Sky Foot & Ankle is here to help. The earlier a bunion is treated, the more options are available. New patients are welcome at both our Butte and Bozeman clinics. Some insurance plans require a referral, so check with your carrier.
