What causes thrombophlebitis?

ANSWER

First, a blood clot forms. This can be due to several things. Most often, it’s caused by blood not moving the way it should through the leg veins. It can happen if you’ve been on long-term bed rest, such as after a major illness or surgery.

Blood clots can also form if you’ve had to sit for a long time in a place where you couldn’t stretch your legs, like on a long flight or drive.
