A bunion (hallux valgus) is a painful bony lump that can develop on the side of your foot and affect how you walk
Hallux valgus refers to the outward deviation of the big toe (1st metatarsal phalangeal joint), typically associated with over-riding of the 2nd toe due to over-crowding. And as a result of friction and pressure, the inner aspect will usually become very prominent, often inflamed and painful (bunion).
