Do You Have Pain or Swelling in Your Leg? It Could Be a Blood Clot
Pain or swelling in one leg can sometimes signal deep vein thrombosis, a blood clot that develops in a deep vein. McLaren Greater Lansing interventional cardiologist Dr. Peter Burke warns that the condition can become dangerous if part of the clot travels to the lungs. Symptoms may include swelling, tenderness, warmth or changes in skin color, although some people have few obvious signs. Suspected blood clots require prompt medical evaluation.
A pulmonary embolism occurs when a clot blocks blood flow in the lungs. Sudden shortness of breath, chest pain, fainting or other severe symptoms require emergency care. Risk factors for deep vein thrombosis can include recent surgery, prolonged immobility, cancer and certain medical conditions. A clinician may use imaging and other tests to determine whether a clot is present.
McLaren Greater Lansing operates a venous thromboembolism clinic for patients who need evaluation and ongoing management. Treatment choices depend on the location of a clot, the patient's risk factors and other clinical findings. People should not attempt to diagnose or massage a suspected clot themselves. The hospital's May 2026 announcement emphasizes recognizing warning signs and seeking appropriate care.
