I live just outside Norwich and go to the NNUH ( Norfolk & Norwich University Hospital ) about my ms. Have a look at the nnuh website, there are a couple of neuro consultants who specialise in ms, the names that spring to mind are Dr Martin Lee and Simon Shields.
I think there are 4 specialist neuro nurses at the moment and they know about all different neuro diseases, i.e MS, Parkinsons etc. Contacting them is a bit hit and miss but they do have direct dial numbers or some of them have their own secretaries you can speak to. Usually if you leave a message, some action will be taken by them.
There is also an ms society branch in Norwich and most Gp surgeries have contact details for community physiotherapists if needed.
If you are moving to the Kings Lynn or Great Yarmouth district then I assume you will be under the Queen Elizabeth or the James Paget hospitals respectively, I’m afraid I don’t know anything about the services they provide in respect to ms.
I’m sorry but I can’t provide any info on social services as I’ve never had to use them yet. Norfolk County Council website might be a good place to start as to what services are available.
Hope this helps.
