It may allergic or idiopathic.
Avoid soap bath.
Avoid contact with dust,grass,wool,plastics or any suspected allergen.
Take short and repeated course of antibiotics.
Take antihistaminics to relieve itching.
You may take steroid

Apply antibiotics till the lesions become dry.. Then, apply stroid cream
and worries,which may exacerbate the lesions.
You may be improved , however ,you can consult dermatologist
I hope you got my answer.
