Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
hives and rashes all over the body along with swollen face and breathing difficulties seems to be most probably due to allergic reaction and can be due causes like any food or medication while can be due to causes like
Contact Dermatitis caused due to surface allergens like poison ivy, detergents, skin cosmetics, soaps etc..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like 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 avoid exposure to it to prevent
allergy attack..
The allergist can advise to oral anti allergics as well as injectable
steroids for relief..
Intravenous fluids and steroids can also be advised..
As of now you can take anti-allergics like Levocetrizine,
Allegra to control the itching and swelling..
Do cool compresses..
Application of calamine lotion can help in soothing the skin..
Taking Steroid inhalers can help..
You can also be instilled an Immunotherapy that will help in reducing the severity and frequency of allergic attack..
Hope this information helps..
Thanks and regards..
