Thanks for writing to us.Atopic dermatitis
is an allergic manifestation which gets precipitated by warm climate and sweating.
You should consult with internal medicine specialist/ dermatologist
and should go for thorough check up. Treatment depends on clinical examination.
You should apply parmethrin lotion along with calamine
on affected site.
You can use steroid ointments
. Long-term management may include treatment with an allergist to control internal allergies and a dermatologist to monitor the skin-care component.
I do hope that you have found something helpful and I will be glad to answer any further query.
