What is going on in the life of Erin & the medical front

ok, so my MS has been a little topsy-turvy as of late.  I already let you all know that I did rehab for a week @ St. Agnes Hospital.  Well, I have also gone off of my Betaseron, which was the "disease-modifying" injectioins that I was doing.  I did my last injectioin on May 4th.  I will be switching to Tysabri, which is an infusion treatment every 28 days.  The reason I am already off the Betaseron is that I need to be clean of that med for 4-6 weeks before starting the Tysabri.  I am in the interim now, and I am doing ok.  I have a doc. appt. on June 4th to get the process started with Tysabri.
