causes of toes curling up
You are here. Definition. A claw toe is a toe that is contracted at the PIP and DIP joints (middle and end joints in the toe), and can lead to severe pressure and pain. Ligaments and tendons that have tightened cause the toe's joints to curl downwards. Claw toes may occur in any toe, except the big toe. There is often discomfort at the top part of the toe that is rubbing against the shoe and at the end of the toe that is pressed against the bottom of the shoe.
