I agree with Keepingfaith, dig deeper.
It really irks me when we go to the doctor because something isn't right and they tend to downplay it and say it's only stress. I don't see how 'stress' can make your body go numb and lose your taste, etc.

Don't worry about being looked at as 'crazy', and don't be embarrassed to go back and demand better than that. You aren't crazy. You want ANSWERS.

I hope you get some straight answers soon by a doctor who will take the time to hear you out and check into this.
