my full body sfn started about the age of 35 after my second child, no pain at first, just funny feelings in feet, and when abroad in hot weather, got a raindrop feeling all over my body. Pain only started when neuro suggested it was SFN, when I read all the horror stories the panic set in, then the pain began! Panic is defo played a role in the pain! I have calmed down now and so has the pain!
