Phlebitis is a local, painful inflammation of the wall of a blood vessel. This inflammation is caused by the development of a clot in a superficial vein. This is a vein, which runs just below the skin. Phlebitis usually occurs in the leg, but it can also affect the arms. Phlebitis is generally harmless with few symptoms.
Phlebitis is usually caused by varicose veins, but it can also be caused by physical injury (for example by falling, punchung or stabbing), by irritation due to, for instance, an infusion needle, allergies and other inflammatory sources in the body. Phlebitis often also occurs as a side effect of administering chemotherapy into the artery where the chemo has been run into.
Mostly, phlebitis occurs spontaneously. Risk factors for the development of phlebitis are:

If, on the other hand, extensive phlebitis takes place or if phlebitis is accompanied by many symptoms, wearing compression stockings may alleviate the problems. Simple anti-
Phlebitis generally passes on its own and there’s no reason for concern. In rare cases, the condition may, however, get dangerous. For example blood clots (thromboses) may arise, which block the blood vessels and, if they come loose, may lead to heart failure or respiratory failure.
