Phlebitis is also sometimes known as superficial thrombophlebitis or superficial vein thrombosis.
Phlebitis usually affects the veins in the legs, but you can also get it in your arms or neck.
- throbbing or cramping pain in your leg, arm or neck
- sudden swelling in your leg, arm or neck
- warm skin around the painful area
- red or darkened skin around the painful area
- swollen veins that are hard or sore when you touch them
It's important to get these symptoms checked in case it's something more serious like deep vein thrombosis (a type of blood clot).
