Hello, 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.
