Forgive me if I have misunderstood your message. Are you saying that you have not seen a neurologist since you moved to Surrey in 2014? When you write ‘Dr’ I am unsure if you mean your GP or a specialist.
If you have not seen a neurologist for at least three years then your GP should make an urgent referral for you. In the meantime do you have a MS nurse to whom you can speak?
As for Sativex, I am sure that you are aware that it has been approved by NICE but that the NHS will not fund it under its prescription scheme. Neurologists can plead to the NHS by making an individual referral for funds. What the criteria might be and what is the likelihood of success in Surrey, only your neurologist can determine. In England, the postcode lottery applies as always.
Although us with PPMS are perhaps not seen as often as our fellow RRMS sufferers, I seem to be on a two year cycle in Suffolk, I have good access to a MS nurse and she has been extremely helpful and supportive.
I hope that you are seen soon to discuss your options with Sativex. In the meantime, the only options are CBD, supplements and physiotherapy.
