A bunion (hallux valgus) is an inflamed, bony bump that forms at the base of the big toe where it joins with the foot. Bunions result from the big toe pushing against the neighboring toe, forcing the joint of the big toe to swell and bulge out. This common deformity can be caused by wearing shoes that are excessively tight or can develop as a result of a genetic structural defect or a medical condition, such as arthritis. Bunions tend to slowly worsen over time, and, if they become too severe, can hamper the ability to walk, increasing the risk of developing arthritis and/or bursitis.
