The signs and symptoms of thrombophlebitis depend on the type. Deep vein thrombosis (DVT), which occurs in the deep muscles of the legs, frequently has no symptoms, and patients may only become aware of a problem when an embolism develops. Depending upon where the embolism occurs, symptoms of an embolism can include:

About half of the time, patients with DVT will experience symptoms directly related to the DVT. These include:

• Swelling and tenderness, which may or may not occur in the affected area
• Inflammation
• Discoloration in the skin
• A throbbing or burning sensation
• Pain during movement
• Fever
• Increased heart rate

By contrast, patients with superficial vein thrombosis (SVT) more often have signs and symptoms, although the condition is frequently considered benign. Signs and symptoms of SVT generally include:

• Swelling and tenderness in the affected area
• Inflamed veins that are visible through the skin or feel hard to the touch
• A throbbing or burning sensation just below the skin surface.
