Symptoms can involve several parts of the body, or only one. Although almost any area of the body can be affected, most people have few, if any, symptoms. Less than half of people with sarcoidosis need any treatment. The most common symptoms involve the lungs, skin, eyes and liver. People with sarcoidosis may have a cough or chest pain.
Some people have breathing problems, but most people have few or no breathing problems.
These symptoms can make it hard to see, but they rarely cause blindness. Eye symptoms usually include dry eyes but can also include swelling of the tear gland that makes the eyes water. The liver can become enlarged. Symptoms are much less common in the other areas of the body. Sarcoidosis can cause the heart to beat abnormally.
