Hello,
Hives on the body seem to be most probably due to an
allergic reaction and in case if you have not changed any foods, medicines, shampoo, soap or laundary, etcetera then it can be due to other causes like bed bugs, environmental irritants, etcetera.
I would suggest you consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like allergic tests like
Patch test, RAST test, food challenge test, etcetera 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-allergic 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
immunotherapy that will help in reducing the severity and frequency of allergic attack.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
