13. Chest pain
Similar to shortness of breath, chest pain may also appear as a respiratory symptom in severe cases such as pulmonary embolism or milder cases such as pulmonary infections. A doctor should carefully examine chest pain because systemic lupus erythematosus patients have a higher risk of cardiovascular problems, such as heart failure, coronary vasculitis, and coronary artery disease. All of these complications of systemic lupus erythematosus should be adequately assessed, and the first step is to talk to your doctor about your symptoms.
