Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
severe itching and soreness over the body along with swelling or hives seems to be most probably due to
allergic reaction..
It can be due to any food or medication while skin cosmetics, poison ivy etc can be a cause..
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..
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..
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..
Dr.Honey Nandwani Arora..
