How to treat phlebitis

Fact Checked

Phlebitis is a condition where the veins becomes inflamed and result to pain and swelling. Inflammation caused by a blood clot or thrombus is called thrombophlebitis. This condition usually happens in the veins of the leg and can also affect the veins in the arms.  The superficial veins and the deep veins are the two sets of veins found in the arms and legs.

Superficial phlebitis affects the veins on the surface of the skin and can form blood clot and result to pain and inflammation. Superficial phlebitis in the legs is associated with varicose veins.  Phlebitis in the deep veins or larger blood vessel is also called deep vein thrombosis which affects the deeper veins found in the arms and legs. Large blood clot can develop, which can break off and spread to the lungs and result to pulmonary embolism which is a serious condition.

Gradual development of a tender red area along the superficial veins on the skin.
