Recognizable Symptoms Of Lupus
Nephritis

People with lupus may experience nephritis, or inflammation of the kidneys, which makes it harder for them to filter waste and toxins from the blood. The Lupus Foundation of America suggests that nephritis may develop five years after first being diagnosed with the disease. Symptoms may include high blood pressure and swelling in the feet and lower legs. Blood in urine is also common and so is going to the bathroom more frequently at night. If urine is darker than normal, this could be a sign of nephritis.
Problems Breathing

If you are suddenly experiencing problems breathing, this may be a sign of lupus. Lupus affects the pulmonary system by causing inflammation of the lungs and blood vessels, which can restrict oxygen flow to the rest of the body. Breathing difficulty may be one reason for unexplained fatigue. You may also notice it feels harder to breathe due to the increased pressure on the diaphragm. Some people with lupus experience pleuritic chest pain when they try to breathe. Lupus can also shrink the lungs over time.
