A bunion, generally referred to as a bunion, can cause pain and deformity in the foot that can affect quality of life. A bunion, commonly known as a big toe, is a common foot deformity that manifests itself as an inclination of the thumb to the outside of the foot and an inward convergence of the first metatarsal. When wearing high-heeled or pointed shoes, walking, etc., the affected area is subjected to friction and extrusion, which can cause foot pain and further aggravation of the deformity. Gradual aggravation of valgus may cause the 2nd toe to be pushed to the dorsal side by the 1st toe, and the interphalangeal joints to be flexed. Because of the pain and deformity, it may affect the daily activities of the foot, the free choice of shoes, etc., and even affect the daily life, so if there is any discomfort, it is recommended to consult a doctor in a timely manner.
