I also was recently diagnosed with Still's Disease and have so many questions about other people's symptoms, I do question often because it isn't something you cannot test for. I constantly get rashes, I've had about four different kinds of rashes, and when this all started I had Very itchy skin and even sometimes got hives at the most random of times. I also have psoriasis, which a naturopath I recently saw said was linked...all because it is all autoimmune related. He said something turned this switch on in my body, and hopefully something will turn it off....My general doctors have me on Prednisone and Clarithromyasin, and it gets very frustrating getting yeast infections from it constantly. All in all, there are over 80 autoimmune disorders, and I think that when you have an array of them; psoriasis, irrital bowel syndrome, asthma, eczema etc. this can sometimes just happen? But I definitely think it is connected.
