Does anyone know what this is, so when someone breathes on or touches or kisses the back of my neck I get a really uncomfortable tickling sensation on the left of my back, under my shoulder blade. If that person keeps doing what they are doing I have it a multiple amount of times. 

I don't know if any of this information will help. I told my mum and when she was little her dad used to shave her heard she hates being touched on the back and the neck and when her dad done this she used to faint.

Also, about 5 years ago, I did hurt my back we went to the doctors but i had just bruised all of my back but I was in a lot of pain- I was thinking maybe something wrong with my nerve there but I don't know, I have gone on google and can't actually find anything on what I have been experiencing. 

Thank you!
