A bunion deformity, also referred to as a hallux valgus deformity, is a common and often painful foot condition characterized by a bony bump that emerges at the base of the hallux. This protrusion is a result of the metatarsal bone of the great toe shifting away from the center, causing the big toe itself to turn inward towards the other toes. https://whatispodiatry.com/what-are-bunions/
