What causes hives and angioedema, are they contagious?

Hives appear in cases when histamine and other compounds are released from cells called mast cells, which are usually found in the skin. Histamine causes fluid that may lead to swelling in the skin to leak from blood vessels.

Hive may be a common skin infection, but they are not contagious. Regardless, when this skin infection occurs, they usually resolve on their own over a given period and are in fact, rarely medically serious. Some hives may be caused by allergy to certainreactions to issues like medications, preservatives, food and food colouring, insect stings and bites, and different organisms. However, in most cases, there is no specific cause of hives.

Generally, causes of hives may include allergic reaction to the following

  • Foods: certain food like milk, peanuts, eggs, tree nuts, and shellfish. Fruits like citrus fruit can also cause hives.
  • Insect bites and stings

OUR PATIENTS REVIEW

Quotes

ReviewsI was suffering from terrible allergies. Over the counter medications didn't help much and life was going from bad to worse. I started spending more time browsing the web for a solution. Then, a colleague recommended me the Clear skin Clinic. I went for the first consultation without much expectation. But the moment I arrived, all my worries were put to rest. I underwent the pinprick allergy testing to learn that I was allergic to dust mites. Since then, I bought cleaning products and vacuums as suggested by these people and that helped. I suffer seldom now, thanks to Clear skin Clinic.

ReviewsMy eczema had been a constant problem since I was young and I had treatment of different sorts with mixed results. It was a colleague who suggested that I go to Clear Skin Clinic and see if they could help. I was so impressed by the staff at the clinic all of whom were kind and efficient. I have started treatment now and my skin is looking so much better.
