If less than a week? Call your neuro and set up an appt for later this week! DO NOT let him/her palm you off to an ER! MAKE them take crucial tests that could help in getting an ultimate diagnosis.
MAKE them measure how much you are losing in sensitivity! IF they refuse? Set yourself up for an emergency appt w/another doc! THIS IS NOT a thing to be laid back about? Throw a sweet mild temper tantrum to your doc! You need to be evaluated and soon! THIS WEEK!
Please if this doc won't listen? Try another one.... If none of that works? Then the ER is your option and I hope and pray you get a LIVE resident when you arrive.
Please let us know how you are doing from now on as when you can? I am worried, I've been there! 's!! - j
