What are the symptoms of having phlebitis?

Pain: Phlebitis means that you have an inflamed vein. Usually the vein becomes hard, the skin over it swells, turns red, feels warm and hurts. It is important to know whether you have a blood clot or not though. That takes getting an ultrasound. If you have symptoms like that, you should see a doctor.

Pain, swelling: Inflammation of a vein is phlebitis, and there is pain, swelling, and at times reddish discoloration especially when the vein is close to the skin. In deep venous phlebitis (dvt), there may be only slight pain like a pulled muscle, and swelling may vary, and the discoloration not so evident unless there is a lot of clot present and the leg may become purple. Phlebitis can occur anywhere.

Inflammation: Phlebitis is an itis (inflammation) of a phleb (vein). We usually think of phlebitis as being a problem involving a clot in a superficial vein. Typically the symptoms are those of inflammation and include pain, swelling, warmth, and redness. The pain is often very localized. Even though superficial, it is important to make sure that the clot doesn't even into a deep vein with ultrasound.
