Warning Signs of a Blood Clot
Understanding the internal symptoms of deep vein thrombosis (DVT) and pulmonary embolism (PE) is critical for early intervention and saving lives.
Sudden Swelling
Persistent Pain
Typically occurring in one leg or arm, this localized swelling may happen gradually or appear suddenly without a clear cause.
Pain often feels like a sharp cramp or intense soreness. It usually starts in the calf and may be tender to the touch.
Skin Discoloration
The skin over the affected area often becomes noticeably red, blue, or pale, and may appear shiny due to the restricted blood flow.
Local Warmth
You may notice that the skin in the painful or swollen area feels significantly warmer than the rest of your body when touched.
Shortness of Breath
Sudden, unexplained shortness of breath is a primary warning sign that a clot has traveled to the lungs, a condition known as PE.
Acute Chest Pain
A sharp, stabbing sensation that intensifies when you take a deep breath or cough. This requires immediate emergency medical attention.
Understanding the Risks
Recent surgery or major physical trauma, particularly involving the lower limbs
Extended periods of immobility, including long-distance travel and hospital stays
Genetic predispositions and a family history of blood clots or clotting disorders
Active cancer or chronic medical conditions such as heart disease and inflammatory disorders
Pregnancy and the initial six-week postpartum period when risk is significantly elevated
The use of hormonal contraceptives or hormone replacement therapy (HRT)
