Bunions are bony protrusions that develop at the base of the big toe, leading to a misalignment of the joint. They often result from the prolonged pressure exerted on the foot, faulty foot mechanics, or genetic predisposition. Symptoms of bunions can include a visible bump at the base of the big toe, pain or soreness around the joint, redness and inflammation, difficulty finding comfortable footwear, and the formation of corns or calluses on the affected area.
