It seems that you are having atopic diathesis.
Thats why your skin is dry.. Xerotic.
And you are having less perspiration.
You are having itchy papular eruptons.
It may be prurigo
You had eczema
All these suggest that you are having atopy.
Oral antihistaminics,tappering dose of steroids
and short course of antibiotics will be helpful.
Application of mild steroids with antibiotic cream improve the lesions.
Avoid soap at bath, use dettol liquid in water.
Avoid stress and worries.
STILL, YOU CONSULT DERMATOLOGIST
I hope you got my answer.
