Sarcoidosis in my early 20s. I was lucky,it cleared up and went away with no more effects. It didn't have a lot of symptoms. I had a sore chest, and felt tired, and had lesions on my legs- that was the worst.
I now have an autoimmune thyroid disease, Hashimotos,runs in the family. I seem to get autoimmune things. I develop allergies- penicillin, sulfas, and most recently pistachios and cashews. However, I'm not like the bubble boy. THe doctor just said I'm prone to developing allergies.
You can catch more flies with honey than with vinegar. That's great...if you want to attract vermin.
