A bunion is a bony bump that forms on the joint at the base of your big toe. It occurs when some of the bones in the front part of your foot move out of place. This causes the tip of your big toe to get pulled toward the smaller toes and forces the joint at the base of your big toe to stick out. The skin over the bunion might be red and sore.
Wearing tight, narrow shoes might cause bunions or make them worse. Bunions can also develop as a result of the shape of your foot, a foot deformity or a medical condition, such as arthritis.
Smaller bunions (bunionettes) can develop on the joint of your little toe.
BIG TOE & FOOT ANATOMY
The signs and symptoms of a bunion include:
A bulging bump on the outside of the base of your big toe
Swelling, redness or soreness around your big toe joint
Corns or calluses — these often develop where the first and second toes rub against each other
Ongoing pain or pain that comes and goes
Limited movement of your big toe
There are many theories about how bunions develop, but the exact cause is unknown. Factors likely include:
Inherited foot type
Foot stress or injuries
Deformities present at birth
Experts disagree on whether tight, high-heeled or too-narrow shoes cause bunions or whether footwear simply contributes to the development of bunions.
Bunions might be associated with certain types of arthritis, particularly inflammatory types, such as rheumatoid arthritis.
Treatment options vary depending on the severity of your bunion and how much pain it causes.
Nonsurgical treatments that may relieve the pain and pressure of a bunion include:
Wear roomy, comfortable shoes that provide plenty of space for your toes.
Over-the-counter, nonmedicated bunion pads or cushions may be helpful. They can act as a buffer between your foot and your shoe and ease your pain.
Acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve) can help you control the pain of a bunion. Cortisone injections also might help.
Padded shoe inserts can help distribute pressure evenly when you move your feet, reducing your symptoms and preventing your bunion from getting worse. Over-the-counter supports can provide relief for some people; others require prescription orthotic devices.
Icing your bunion after you've been on your feet too long or if it becomes inflamed can help relieve soreness and swelling. If you have reduced feeling or circulation problems with your feet, check with your doctor first before applying ice.
If conservative treatment doesn't relieve your symptoms, you might need surgery. Surgery is not recommended for cosmetic reasons; only when a bunion causes you frequent pain or interferes with your daily activities.
There are many surgical procedures for bunions, and no one technique is best for every problem.
Surgical procedures for bunions can be done as single procedures or in combination. They might involve:
Removing the swollen tissue from around your big toe joint
Straightening your big toe by removing part of the bone
Realigning one or more bones in the forefoot to a more normal position to correct the abnormal angle in your big toe joint
Joining the bones of your affected joint permanently
It's possible that you'll be able to walk on your foot right after a bunion procedure. However, full recovery can take weeks to months.
To prevent a recurrence, you'll need to wear proper shoes after recovery. For most people, it's unrealistic to expect to wear narrower shoes after surgery.
Talk to your doctor about what you can expect after bunion surgery.
