I want to post this symptom to see if anyone else has experienced this. I feel that most people on this site experience things such as back pain etc. and not really inexplicable nerve type stuff ( I am hoping I am wrong, not that I would wish this on anyone). I have had the prickly feelings three times over the past 10 years. When it disappears it totally goes away but when it reappears it is fairly constant except when I am in bed at night - it disappears then. I have been tested extensively including blood work, MRI's, nerve tests, neurologist visits- the works and everything comes back normal. My first bout was after a flu and my last bout was after a two month period of unrelenting stress. It seems to have clicked on and I haven't been able to turn it off. It has really worn me down. Can anyone relate? Thank you!
