Superficial Thrombophlebitis
The name is a mouthful, so here is the short version. Cleveland Clinic describes superficial thrombophlebitis as a blood clot that develops in a vein close to the surface of your skin. That nearness to the surface is what separates it from the deeper clots covered elsewhere in this journal, and a Cleveland Clinic guide to deep vein thrombosis explains the deeper kind if you are unsure which one worries you.
Cleveland Clinic adds that blood clots can form inside varicose veins, causing this painful, but usually not dangerous, condition. It also says that superficial thrombophlebitis goes away in a few weeks, while recovery from other venous diseases can take more time. For wider context, its overview of types of venous disease puts the surface clot next to its relatives.

What to do first
A good first step costs nothing and needs no skill. Note where the sore spot is, roughly how big it is, and whether it changes over a day or two. A written note or a phone photo gives a clinician something real to look at. If the area gets worse, spreads, or you cannot tell whether the clot is near the surface or deeper, stop experimenting and ask a clinician. A Cleveland Clinic guide to varicose veins is useful reading while you wait for that appointment.
