Have you mentioned to the people that set up the appointment that if there are any cancellations that you would come in when ever there was a cancellation? Sometimes you can get in a lot faster (you might call first thing in the morning or at the end of the day - then that way they would know of the cancellation by then).
Also, my daughter was diagnosed with hemiplegic migraines (I don't know if that's what you have at all), but she was going numb completely on her left side.
I hope you get into the doctor soon and get answers. Will be praying for you.
God bless you.
