Lupus Warning Signs: How to Recognize and Manage This Elusive Autoimmune Disease

19. Blood Clots
Lupus increases the risk of dangerous blood clots, leading to deep vein thrombosis (DVT), stroke, or pulmonary embolism. Symptoms include swelling, redness, or pain---often in one leg.
Why it's urgent: If you experience sudden shortness of breath, chest pain, or one-sided swelling, seek medical help immediately, as these could be signs of a life-threatening clot.
