m glad that you are getting physical
therapy treatment - as well as an eval for PT, OT,
speech, etc. It is scary that your symptoms started not even a year ago and they're already suggesting a wheelchair.
If you have PPMS, like I think I have (even though my DX is RRMS), then unfortunately, the answer would be no, there are no disease modifying drugs for people with PPMS. However, if you have secondary progressive, then some DMDs may work for you.
