I have been to see her Consultant today. After at least two years' waiting with no disease-modifying drugs available (previous treatments didn't work or caused bad reactions), subject to a couple of checks, I should be approved for 'Fingolimod', a new medication recently approved by the EU and now N.I.C.E. It is one pill taken every day, so no nasty admin methods. It 'works' by causing the white blood cells which would otherwise attack myelin surrounding nerves to be gathered to the lymph nodes instead. It apparently has a success rate between 60-70% which is unprecedented in the MS treatment field. So,I am truly thankful, and hopeful.
Here is a link to more imformation about it if you are interested.
