Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain red spots over the body along with pimple like spots and itching can be due to causes like
Contact Dermatitis caused by any detergent, skin cosmetic, perfumes,insect bite, poison ivy etc..
It can also be due to hair
follicle infection or
Folliculitis, food allergies etc..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis and treatment can be done accordingly..
As of now you can give her
anti histamines or anti allergics like
benadryl as it will help in relieving the itching..
Do cool compresses over the spots/bumps..
Avoid any chemical skin cosmetics..
Hope this information helps..
Thanks and regards.
