...I also have a slightly less sensitive spot just below my toes on the same foot.
My left little and ring finger also have a tiny area on the tips which creates a small electric shock like prickly feeling when touched, they are also slightly less sensitive, and in general most of my left side feels slightly less sensitive than the right in comparison.
I have no pain, or weakness. I'm 26, generally healthy and concerned.
Could this be something to do with my circulation - i get very blotchy red/white palms - but i've always had this.
My foot has been like this for 2 years. The hand thing is more recent (last few months) and seemed to occur after a sharp pain whilst playing guitar.
Please help, i'm worried.
