Cindy.
I agree w the others that this is a tough call.
If you are to the point of putting the house on the market and moving closer to your family because of this, it might be worth a trip to the ER to be seen by a neuro resident.
Here's the upside: It will document this in case it is resolved by May. You may get an MRI and you can mention w/w out contrast. Speak up politely.

You may also get treated w steroids to end this exacerbation if that is what it is.
Make sure to tell the ER that the Neuro's office told you to come
Best to you whatever you decide.
