Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
Chronic hives is commonly due to
allergic reaction that can be due to a number of allergens like certain foods and medicines, skin cosmetics, leather, latex, air allergens like animal danders, pollen, certain trees, grasses etc.
So you need to get checked by a Specialist like an Immunologist and get evaluated.
A clinical examination and an
allergy test can be done for confirmation of the diagnosis and treatment can be done accordingly.
For now you can consult an Emergency room and get checked and they can advise you anti allergic medicine like
Fexofenadine or Levocetrizine and a
steroid shot if the symptoms are severe.
Do cool compresses and apply
Caladryl lotion.
Hope I have answered your query. Let me know if I can assist you further.
