A bunion (also referred to as hallux valgus) can be described as a bump that forms on the side of the base of your big toe. This bump occurs due to changes in the orientation of the bones at the front part of your foot. This causes the big toe to be pulled toward the second toe, causing the joint at the base of the big toe to stick out and therefore producing the standard bunion bump.
Bunions are a progressive issue beginning with the leaning of the toe and with time the angle of the bones can get increasingly prominent. Due to the bump rubbing on shoes it can become irritated and the skin over the bump can be red and tender to the touch.
Bunions are the most common problem that affects the front part of the foot in adults. They are more common in women than men and are more likely to occur as you get older. There is also an occurrence where this can happen on the joint of the little toe – this is called a bunionette.
