So, I had the test last week, and all I could think was how laughably imprecise it was.

As expected, I was a bit abnormal but not enough to say anything for sure. My cold/heat-detection tests were in the normal range, every time, at every site they did... and they were the most important ones apparently.

My cold/heat pain thresholds were often elevated but I found it quite a tricky test. At what point do you say something's painful? Yeah, you can feel it, yeah, it's cold, but is it painful? For me to actually click a button to say I'm feeling pain, it'd probably actually need to be hot enough to cause some damage, which obviously it can't do.

So, I'm still in no-mans land with no SFN diagnosis either way, and am waiting to see if the doctors here in the UK will give me a skin biopsy, which is still in trials here and not widely used. Otherwise, I am going to have get it done on my next visit to the US, or see if I can a pack sent over an analyzed stateside. What a pain.
