Good evening @roslyn2314, Greetings......I just read your posts. Let me see if I understand what you are asking. You want to know about diagnostic tests for SFN because you are faced with a long wait for clinicians in Australia.

How was your SFN diagnosis made? Did you have the skin biopsy which is usually done around your ankles? That is the only definitive test I know of for SFN. Were you told the probable cause of your condition? For example, mine is the result of a long series of accidents and surgeries that created a traumatic form of neuropathy.

You also ask about a cure. Unfortunately, there is no cure for neuropathy of any kind at this time. The key is to find a way to ramp up the replacement of the nerves which no longer serve you. At this point, the process takes way too long even though our bodies work hard at it. So we are left with a strong need for something that will mask the pain caused by the lack of sufficient nerves.

I am fortunate to have found the support of medical cannabis. It doesn't wipe out the pain and insufficient functioning of muscles. It just keeps it under control so that we can continue to live and enjoy a reasonably stable existence

Can you purchase medical cannabis in your area?

May you be free of suffering and the causes of suffering.
Chris
