Just to say, my neuro does not like to precribe steroids for ON either unless it is causing terrible problems, so there’s nothing particularly unusual about this, and it does not mean that anyone is being remiss, or that you are not getting the best care.
Personally I don’t like to reach for the steroids too soon either - it’s nice to have something left in the locker for when the wheels really come off. But it is also a comfort to know that the option is there if I’m in bad trouble.
BTW my relapses tend to come in flurries too - it is rare for me to have a relapse with only one symptom. When my MS is being active it likes to attack across a broad front.
I hope that this relapse passes quickly and that you start to feel much better very soon.
