Hi,
You are having generalised
pruritus, more on legs.
There are many causes.
You should undergo for investigations.
DM,HIV,thyroid dysfunctions,other endocrinopathies,anaemia, blood diseases,
connective tissue diseases, malignancies, drugs,stress,anxiety,xerosis, weather..etc may cause pruritus.
You are right, in your case it may be weather.
Take oral antihistaminics.
Take
steroids in tappering dose.
Local mild steroids and moisturiser may be applied.
Avoid soap bath.
Dettol liquid may be used for bath.
You
consult dermatologist.
I hope you got my answer.
Thanks.
