Topic Overview

A bunion camera.gif is an enlargement of bone or tissue around the joint at the base of the big toe. The big toe may turn toward the second toe. The tissues around the joint may be swollen and tender.

A bony bump at the base of the little toe is called a bunionette camera.gif or tailor's bunion. The little toe also bends inward, and the joint swells or enlarges.

You may get bunions if:

  • The way your foot is shaped puts too much pressure on your big toe joint. Because bunions can run in families, some experts believe that the inherited shape of the foot makes some people more likely to get them.
  • Your foot rolls inward too much when you walk. A moderate amount of inward roll, or pronation, is normal. But damage and injury can happen with too much pronation.
  • You have flat feet.
  • You often wear shoes that are too tight.

All of these may put pressure on the big toe joint. Over time, the constant pressure forces the big toe out of alignment, bending it toward the other toes.

Your bunion may not cause any symptoms. Or you may have pain in your big toe, red or irritated skin over the bunion, and swelling at the base of the big toe. The big toe may point toward the other toes and cause problems in other toes, such as hammer toe. A bunionette can cause similar symptoms at the base of the little toe.

Your doctor will ask questions about your past health and carefully examine your toe and joint. Some of the questions might be: When did the bunions start? What activities or shoes make your bunions worse? Do any other joints hurt? The doctor will examine your toe and joint and check their range of motion. This is done while you are sitting and while you are standing so that the doctor can see the toe and joint at rest and while bearing weight.

X-rays are often used to check for bone problems or to rule out other causes of pain and swelling. Other tests, such as blood tests or arthrocentesis (removal of fluid from a joint for testing), are sometimes done to check for other problems that can cause joint pain and swelling. These problems might include gout, rheumatoid arthritis, or joint infection.
