Some bunions need surgical correction. Never consider bunion surgery for cosmetic reasons. Most not only remove the bump, but correct what causes the bunion so that it does not grow back. Your orthopaedic surgeon will discuss with you what procedure, if any, is appropriate. Most corns result from pressure when the skin is squeezed between the bones and shoes.
Corns can appear over almost any bone of the foot, but most commonly over misshapen, hammer toes.
Here the hammer toe causes continued pressure which results in skin irritation and corn formation. Sometimes you will need surgery to relieve the underlying pressure, but a toe pad from a drugstore can treat a mild problem. If the problem persists, your physician can decide if you need surgery. Again, as with bunions, changes in shoewear will often be all you need. All swellings of the great toe are not bunions.
