sorry to hear this, what is the neuro's answer as to why it isnt getting done.

if neuro says he sent it out I would ask him to fill the papers in again and you will pick them up and send it priority mail and with delivery confirmation....

I think I would let doc know how this is effecting you and how the stress is not helping this flare,

with the delivery confirmation number you can see what day and time it was delivered

I hope this gets resolved
