Acute sarcoidosis is often characterized by fatigue, fever, generalized muscle aches, difficulty breathing (dyspnea), joint pain, swollen glands, skin eruptions,
eye irregularities,
and/or other symptoms. In the subacute form, affected individuals may experience no symptoms (asymptomatic), even with organ involvement. In the chronic form of sarcoidosis, symptoms may appear slowly and subtly, and may persist or recur over a long time span.
