What is Thrombophlebitis?

The term ‘phlebitis’ means inflammation of the vein. Thrombophlebitis occurs when one or more blood clots form in a vein, causing inflammation, and blocks blood flow. Thrombus in your veins causes pain, irritation and may even block blood flow in veins. Thrombophlebitis typically occurs in the leg veins, but can occasionally occur in arm veins.
