PPMS (Relapsing)

Hi guys, Latest report from Consultant says I suffer from relapsing PPMS I am somewhat confused due to progression with this type expected over years/decades, yet my body says yes to this, I have suffered 2 fairly scary events of sudden decline in my mobility from Jan - April this year with no evidence of UTI’s or virus as a trigger, I feel I’ve come through a crisis now but with more noticeable deterioration in my mobility.

Can anyone else relate to the same sort of pattern, or what are your thoughts on the subject.
