A bunion is a bump at the outside edge of your big toe. As the bump gets worse, it can be filled with extra and fluid.
Bunions form when your big toe slants toward your small toes. High , pointed shoes, or shoes that are too tight or narrow may cause bunions. Bunions often run in families.
To prevent bunions, wear shoes that fit well.
Your doctor may suggest using padded shoe inserts to prevent a bunion from getting worse and using medicine to reduce pain and swelling. You may need surgery to remove a bunion that causes frequent pain.
