I have to go to for an ESA medical next week at 9 am..... I am suffering from a rare form of Parkinsonism called Cortico Basal Degeneration. Am I able question the "examiner" with regard to his/her qualifications to carry out an assessment on my ability to work? I had to give up work esrlier this year and had to stop driving after 44 years on the road. The last 12 were spent as a courier earning my living that way.. I have a Blue Badge (as a passenger) and a 'Disabled Bus Pass'. and receive MA at top rate and DLA at middle rate. Any words of advice and enouragement most welcome.
