Dear none:
My best guess is that you have dyshidrosis, a common, inscrutable, and minor skin affliction which produces little blisters on the palms and/or soles. It isn't fungal, nor are "nerves" likely to be onvolved. (Not that we have a clue as to what else might cause it.) The condition comes and goes. Topical steroids (like Diprolene) help a bit, if the symptoms are worth the trouble.
Causes for most things are unknown, which is one reason "nerves" and "stress" get blamed a lot.
As to what kids learn nowadays . . . . .
Best.
Dr. Rockoff
