Hi and welcom to the forum,
I have never heard of anyone being on Medrol for that long, what are your reasons
for being on it
for such a long period of time? Seems to me that being on it
for that long could be very problematic but I could be wrong, I am sure others will chime in.
As for the DVT I don't believe that is related to MS that is more of a blood disorder if I am correct and MS is a CNS disease.
