Be seen today
Arrange a routine or prompt medical review if you develop a persistent cough, increasing breathlessness, new skin changes, worsening fatigue, joint swelling, or symptoms that return after improving.
Seek prompt assessment for eye redness, eye pain, sensitivity to light, or new blurred vision.
Early treatment can help protect sight.
New palpitations, dizziness, ankle swelling, increased thirst, frequent urination, or possible kidney-stone pain also need medical review.
These symptoms can have causes other than sarcoidosis, but they need urgent assessment.
Every sign above is quoted from the sofidex article on Sarcoidosis. If you are not sure, err upward — it is always reasonable to be checked.
