What is the primary symptom of phlebitis?

The primary symptom of phlebitis is pain and swelling in the vein. Phlebitis, which is inflammation of a vein, often presents with localized discomfort in the affected area. This pain can range from mild to severe and is frequently accompanied by swelling, tenderness, and feeling warm to the touch. These symptoms typically occur along the course of the affected vein and are indicative of the inflammatory process taking place.

While other symptoms such as redness in the skin, fever, chills, nausea, and vomiting may accompany various medical conditions, they are not the hallmark indicators of phlebitis. Redness can also occur, but it is usually a secondary symptom. Fever and chills may suggest a more systemic infection rather than localized inflammation, and nausea and vomiting are not connected to phlebitis at all. Therefore, the focus on pain and swelling makes it clear why this is considered the primary symptom of phlebitis.
