Thrombophlebitis

Thrombophlebitis (throm-bo-fle-by-tis), or just phlebitis, is where a vein becomes inflamed due to a blood clot.

Thrombophlebitis usually happens in your legs, although it can affect other veins. Thrombophlebitis affects your shallow (superficial) veins and is different to a deep vein thrombosis (DVT).

The affected area may be warm, red, swollen and tender.
