This problem does not cause any trouble, but I am curious what it is, and grow more curious as each doctor I have asked has had no clue and never heard of such a condition.
Exactly down the middle, my left half is much more sensitive than my right. This includes my face.
I have been this way since birth.
My right side is considerably insensitive. This includes heat, cold, pain, etc.
I must always hold cold drinks in my right hand; the cold becomes unbearable in seconds in my left hand.
I always discover bruises and scratches on my right side without knowing what I did to cause them. I always know immediately when I bump or bruise my left side.
Because I hold food with my right hand, I often burn my mouth, not realizing how hot the food is. I DO have the same condition inside my mouth, but there is not as large of a difference between the sides.
I sometimes shiver only on my left side.
Brain scans show nothing unusual. Physical tests show a difference in sensitivity.
Has anyone ever heard of this condition before?
