Hello all! I am new here and am hoping to reach out to others. After a lengthy period of high stress, I had been feeling poorly for at least a year...... fatigued, brain fog, slowed cognitive function. In July of 2016, I lost partial vision in one eye suddenly and painlessly. It was diagnosed as non-embolic occlusion due to retinal vasculitis. I was put on massive dose of prednisone/steroid. I finally tapered off August 27, 2017. After a year of testing...nothing ws found. They suspect an auto-immune problem. I was off the steroid for 3 months and feeling fine except for hip pain, when it "attacked" my other "good" eye. I am wondering if it could be caused by a virus or something other than an auto-immune than could be more easily treatable. I am still young and have a young daughter to raise and an elderly mom to care for. I don't want to go blind. Has anyone experienced anything similar? If so, what did you do? Thanks so much for you response in advance.
