The doctor has suggested I have sarcoidosis due to many symptoms and CT of spleen with innumerable lesions. Awaiting CT of lungs to come back along with lab results. I chewed my nails for about a year after having fake nails last October and couldn't seem to stop messing with them. Last week I put cheap fake nails on and when they started popping off, I noticed green stuff. Looks like fungus on 4 nails. One is at center of the nail so am sure this is fungus and they are bothering me again and want to chew them. Could nail fungus and chewing my nails have caused sarcoidosis and could it also have been the cause of my persistant nausea for months now? I will be seeing the doctor soon, but this is bugging me. Could I have prevented this if I hadn't chewed my nails. Also, wonder since my dad and brother also had fungal problems-- could their sudden heart attacks also have been sarcoidosis? Thank you so much.
