Thrombophlebitis occurs because of the inflammation of a blood clot generally in your legs in one or more of your blood vessels.
When a surface vein is affected, a red, hard, and sensitive skin may form along the blood vessel on the surface of your skin.
It is more frequently seen in patients with varicosis.
It is diagnoses through ultrasounds and examinations. Treatment is generally drug treatment, cold applications, and rest. The ultrasound is important to understand whether a clot has formed. The existence of a clot determines the form of treatment.
