Yes, although I no longer have regular relapses/flares, in the
last 13 years, I have progressed some in disability, from
walking with a walker to using the scooter most of the time.

Although I chose to use the scooter at home, because I was
falling so much and no one here to help me up, I still didn't use
my walking so I lost the ability.

I do think that LDN has greatly slowed my progression, though.

She is most likely just progressing in an SPMS mode now.
