I would be pleased to answer your question .
It would be important to rule out parasite bites like Cercarial Dermatitis
which is a common water borne infestation .
it results in the kind of welts on the skin and can peel off .
It could also be due to the Urticarial rash called Prurigo mitis
. You should be taking an anti histamine
from your doctor to reduce the itching and topical steroid
lotion over the areas once a day will help in reducing the itching and heal the lesions completely .
Thanks and Take care
