Bunions are a very common problem. Generally they occur when the forefoot spreads and the big toe then deviates towards the other toes.
The prominent bone at the side of the big toe rubs against the shoe and the skin becomes reddened. Often a sac of fluid called a bursa may develop in the tissue overlying the prominent bone. This swelling, consisting of inflamed soft tissues and underlying prominent bone is what we call a ‘bunion’. If left untreated, they can be very painful.
