Phlebitis
Phlebitis is an inflammation of the vein walls often caused by the formation of blood clots (thrombi). There are two types of flebitis: the superficial surface that occurs in a superficial vein and close to the skin, and deep vein thrombosis, which affects deep veins located in the tissues beneath the skin. In cases of mild flebitis, symptoms may not occur. In other cases, the most common symptoms are: pain, sensitivity, redness (erythema) and swelling of the vein. Mild fever may occur in either superficial or deep flushes. The most common causes of this disease are usually infectious, but can also be traumatic or toxic.
