Toe Injuries and Disorders

Fourteen of the 26 bones in your feet are in your toes. The toes, particularly your big toe, help you move and keep your balance. Playing sports, running, stubbing your toe, and dropping something on your foot can damage your toes. Wearing shoes that are too loose or too tight can also cause toe problems. Certain diseases, such as severe arthritis, can cause toe problems and pain. Gout often causes pain in the big toe.

Common toe problems include :

  • Corns and bunions
  • Ingrown toenails
  • Sprains and dislocations
  • Fractures (broken bones)

Treatments for toe injuries and disorders vary. They might include shoe inserts or special shoes, padding, taping, medicines, rest, and in severe cases, surgery.

Wounds and Injuries

An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.

Other common types of injuries include:

  • Animal bites
  • Bruises
  • Burns
  • Dislocations
  • Electrical injuries
  • Fractures (broken bones)
  • Sprains and strains
