Hi canagirl
Sorry to hear your ER visit was not useful. I had to look up Ativan as it's not a brand name I'm familiar with - expected to see it was some sort of pain reliever like Tramadol but was surprised to see it's from the benzodiazipam class of drugs, often used for anxiety. That they offered you that suggests again that they think your symptoms are imagined!

In your earlier posts I think you said you were in Canada - correct? I'm not sure if there would be many in your area but you might be able to find a Neurophysiologist - a neurologist who specializes in how neurological conditions manifest as physical symptoms in the body. They should be able to recognize the SFN symptoms and recommend the skin biopsy.

Keep working with your good PCP to manage the pain as much as possible - I'm not sure what level of pain reliever medication they can prescribe - or what you've already tried. Maybe they would be willing to consult another doctor within their practice, or elsewhere, to find some solutions.
