Deep Vein Thrombosis Symptoms

Some patients many not experience any noticeable deep vein thrombosis symptoms. Others, however, may experience painful symptoms that usually occur in the leg, as this is where deep vein thrombosis (DVT) is most likely to occur. These symptoms can include:

  • Pain, often beginning as cramping or soreness
  • Swelling in the affected leg
  • Increased warmth in the area of the blood clot
  • Tenderness
  • Reddening or discoloring of the skin in the affected area

If you develop one or more of these symptoms, promptly consult with a physician who can diagnose and treat the condition.

Occasionally, a dangerous complication of deep vein thrombosis – called a pulmonary embolism – may arise. When a pulmonary embolism occurs, a blood clot becomes dislodged from the vein and travels to the lungs, blocking a blood vessel. If not treated immediately, it can result in damage to the lungs or even death. Symptoms of a pulmonary embolism include:

  • Sudden shortness of breath
  • Coughing up blood
  • Chest pain, especially when you take a breath
  • Fainting
  • Feeling lightheaded or dizzy
  • Rapid pulse

If you are experiencing symptoms of a pulmonary embolism, seek medical attention immediately.

Additionally, patients who have previously had DVT may experience a complication known as postphlebitic syndrome, even years after their DVT. This syndrome describes the collection of symptoms caused by damage to the veins from a blood clot. Signs of postphlebitic syndrome are similar to those of DVT, and can include swelling, leg pain, skin discoloration, and skin sores. 

Tampa General Hospital’s experienced physicians can provide treatment to manage deep vein thrombosis symptoms as well as any potential complications associated with the condition.
