Experienced hands: If something can be felt but not seen then often a clinician can determine the most likely diagnosis by palpating the area in physical exam. Superficial blood clots or varicosities are easily palpated, but more serious deep venous thrombosis usually are not. Cysts, lymph nodes, and a variety of skin nodules can be found behind the knee too.

? Clot: If you have a varicose vein and now it is hard, this suggests a clotted varicose vein. This is called superficial phlebitis and can be a complication of having varicose veins. See s vein specialist for an evaluation and, in the meantime, apply wet heat to the area and take ibuprofen.
