i am a 21 year old girl..since 7 years i am suffering from eye pain during movement and reduced vision and this problem recurses after one or two month but MRI reports and other eye check up shows my eye nerve is fine so the doctors were confused and prescribed me oral steroid due to this i gained a lots of weight...my symptoms are just like optic neuritis but no test of blood eye and brain proved that. m i still suffering from optic neuritis? i have migrant and sinus too was it caused by them? how can i be sure about it?
