Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain small pin prick like dots over the body and
severe itching seems to be due to contact
allergic dermatitis..
The common allergens can be Poison ivy, detergents,, latex, leather, skin cosmetics,soaps, certain foods and medications..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like RAST test,
Patch test and food challenge test can help in diagnosis and avoiding exposure to allergen can help..
As of now you can take anti allergics like Allegra or
benadryl and apply steroid ointment like
Cortisone over bumps for relief from itching.
Also do cool compresses over the bumps..
Wear loose fitting clothes..
Hope this information helps..
Thanks and regards.
