Thrombophlebitis is inflammation in a vein in an area where a blood clot has formed. Often the term thrombophlebitis is shortened to "phlebitis."
There are two types of phlebitis.
Symptoms of deep vein phlebitis may include swelling, warmth, pain, or tenderness in the affected area (most often a leg). Chest pain that occurs with deep vein phlebitis may mean a blood clot has traveled to the lung.
Deep vein phlebitis requires evaluation and treatment by a doctor. It is usually treated with medications that prevent clotting (anticoagulants).
