Did the numbness subside? I'm presuming you have never had this numbing feeling before? I have sciatica so I know how annoying and disturbing it is to have a limb be numb constantly.
After taking Buspar for a bit, my eyelid began rapidly pulsating. It was really the worst thing I've experienced and my anxiety went through the roof. Anyway, 12 hours later, it had slowed and then by 24 hours, it had completely stopped. Hope that helps a little.
