question: I am a 29 years old woman. I'm Italian but I have been living in Australia since February 2010. I weight 70 kg and I have broncho pneumonia for three times in my life (when I was 3, 8 and 18). Three months ago I got a bad inflammation in both eyes. Now it's better but it still hasn't gone. I've been taking steroid drops since then. They don't know the cause but they think it might have something to do with lungs. Last Friday I had fever, that lasted for 2 days and half. Then, Monday I woke up with very sore knees and in the space of 1 hour my legs up to the buttocks were covered with red lumps, very sore. I couldn't sleep until I had some paracetamol for the pain. I also sweat all night, and this has been happening even the night when I didn't have fever. What is happening? I read something about sarcoidosis, and seeing the many matching symptoms I am afraid I have it. Is that possible? The doctor doesn't have a clue about the lumps, he thinks it might be part of the flu, but he really doesn't know.
