Almost 4 years ago - I noticed blurred/dim vision in my right eye - after much testing, was told optic neuritis, then maybe optic neuroretinitis - has never improved - still the same after 4 years. Through the use of photography - the doctors say it is still ongoing as they can see changes in the optic nerve inflammation - leading them to believe it is some kind of underlying disease. In addition, I have had several other symptoms including joint pain, debilitating fatigue, headache, migraines, IBS, high blood pressure ( I am 28 years old and have taught fitness classes for 10 years - eat well and exercise alot and have never had a problem with blood pressure), dizziness and blurred vision after exercise that lasts about 10 min. and goes away, extremities like fingers and toes turning white when cold, and other random symptoms. I have had several MRI's, lumbar punctures, bloodwork, and almost every other test imaginable ( tested for all STD's, HIV, Lyme Disease, Cat scratch disease, thyroid, diabetes, and others....)- all showing no signs of any disease. I find it difficult to get any answers - and these symptoms are starting to get in the way of work as well as my life - any information or ideas would be helpful - thank you!
