I have rheumatoid Arthritis, am on Methotrexate, have been for about 12 years, now have developed Hypertrophic Olivary Degeneration, Some of the symtoms are what I have been told Methotrexate can do, has anyone heard of this? I have reduced vision, see double, Loss of Balance, swallowing difficulties, and speech problems, as well as palatal tremor, All coming from a lesion on the brain stem, which is also killing off brain cells. I know no one else with this disease, so anyone else I could talk to would be great.
