Don't worry about your Neurotic re-badging you as SPMS. You have your very own version of MS.Out of the estimated one million sufferers worldwide nobody has MS exactly like yours.
However, your Neurotic along with every other one on the planet has to justify its wages so they try and categorise every case of MS into RRMS, SPMS, Primary Progressive or the mysterious Benign.
You will wake up tomorrow with the same MS as you've had today.The only difference is that the Neurotic has justified its wages and the drug companies will sell more drugs to the NHS,if the Neurotic prescribes any of them to.Don't start thinking that things are different for you...........................................They aren't.
AS for help, your local chapter of the MS Society may be of help,and I suggest you stay close to your GP.
