Many people with sarcoidosis do not have any symptoms. Others have only vague symptoms that can be seen in many other illnesses, such as fatigue, weight loss, fever, loss of appetite, depression, night sweats, and sleep problems. Symptoms depend on the organ involved. Examples include:
- Lungs: Shortness of breath, wheezing or dry cough that may disappear over time
- Lymph nodes: Enlarged and sometimes tender lymph nodes
- Eyes: Burning, itching, tearing, redness, sensitivity to light, dryness, seeing black spots, blurred vision, reduced color vision, and, in rare cases, blindness
- Skin: Bumps, ulcers, or rarely, flat areas of discolored skin that appear mostly near the nose or eyes or on the back, arms, legs and scalp. Painful and tender bumps can also appear on the ankles and shins
- Bones and Joints: Bone lumps (nodules), causing pain in the hands, ankles or other joints
- Heart: Shortness of breath, swelling in the legs, wheezing, coughing, and chest pain.
- The Nervous System: Confusion, disorientation, hearing loss, dementia, dizziness, facial palsy
