Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that rashes over the arms, face, neck and back that seems to be due to
CONTACT DERMATITIS that occurs due to
allergic reaction with the contact of skin with detergents..
I would suggest you to consult an Allergist and get allergic tests like
Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly..
The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avid exposure to it to prevent allergy attack..
You can be advised to take anti allergics like
benadryl and levocetrizine..
Use hypoallergic soaps and detergents..
You can also be instilled an
Immunotherapy that will help in reducing the severity and frequency of allergic attack..
Once the allergen is ruled out avoiding exposure to it can prevent the allergy symptoms..
Hope this information helps..
Thanks and regards.
