1. Swelling in One Leg
Swelling is a classic and common sign of DVT. Unlike the general puffiness you might experience after a long day on your feet, DVT swelling is typically confined to one leg. It often comes on suddenly and may be concentrated around the calf, ankle, or foot.
2. A Persistent “Charley Horse” Cramp
The pain from a blood clot can mimic a severe muscle cramp or a “charley horse.” However, while a typical cramp usually subsides after stretching or walking it off, the pain associated with a DVT persists and often intensifies over time.
3. Pain or Tenderness in the Calf
DVT pain frequently originates in the calf. It may present as a dull ache, a feeling of heaviness, or intense tenderness. The pain is usually more pronounced when you are standing, walking, or bearing weight on the affected leg.
4. Red or Discolored Skin
Because the clot impedes blood flow and causes inflammation, the skin overlying the affected area may change color. You might notice the skin looking unusually red, purplish, or even slightly blue compared to your other leg.
