Hi there,

I have sfn, I am still being investigated for the cause but mine could be linked to metronidazole. I am on amitriptaline and lyrica. I had the skin biopsy by a professor in London. I didn't have pain at the start of mine,it must have been there as I had funny feeling like water drops all over my skin when out in the heat. when I was told by the neuro that it was sfn I googled it and completely panicked, after that the burning started from head to toe, I tried gabapentin but it didn't work. the other two drugs are working OK at the moment touch wood. if I panic it makes it ten times worse.

Do you know what caused your sfn?

I hope you get some relief soon.
