Hello, I was diagnosed with Behçet's disease about 3 to 4 years ago. I originally has genial sores and the doctor had said it was herpes. I was devastated..... they had taken a biopsy and the results came back negative that I did not have herpes. They didn't relate know what I had in the beginning. It was probably the hardest time for me. My doctor than determined it could be behcets and she recommended me to a rheumatologist. Since there is not really a test he reviewed my symptoms and determined that I had Behçet's disease. I have been on multiple medications (steroids). I have been on and off humira. I mainly suffer from mouth sores, body aches and thrush! Currently I am suffering from major thrush I question what causes it and how I could prevent it?
