Deep vein thrombosis (DVT)
Deep vein thrombosis (DVT) occurs when a blood clot forms in a vein. This can cause symptoms like tenderness, skin redness, swelling in the lower leg, or warmth in the affected area. But DVT often causes no symptoms at all.
Symptoms after thrombosis (post-thrombotic syndrome)
Post-thrombotic syndrome can develop after deep vein thrombosis (DVT). The leg swells up and is painful. Over time, the skin might change color and start to itch. There are a number of ways the symptoms can be relieved, like exercise and medical compression stockings.
