Very long shot this, but has anyone, anywhere any advice or encouragement for a persistent and long-standing optic neuritis? Been hospitalised three times, had copious quantities of liquid and subsequently tablet-form cortisone and still suffering from dizziness, dull ache, nausea. Opthalmologists have given up and washed their hands of me - simply don't know what else to do. Any advice would be gratefully accepted. For which, many thanks in advance.
