What Could be the Cause of Hives?

You’ve tried to treat your symptoms with over the counter treatments, but nothing has worked. You seem to always be suffering from hives, itching and swelling of the face, upper body and legs. At this point, you begin to wonder… Is this just a rash? Or what could be the cause of hives?

Introduction

Hives (urticaria) are a skin reaction that usually shows up as raised, red bumps and itching. Hive is an allergic reaction that involves the immune system and lasts for at least six weeks.

There are many possible causes of hives, including certain foods, medicines, and insect bites or stings.

Hives can also be caused by stress, heat, cold, exercise, or even wearing certain fabrics such as wool or synthetic polyester.

If you have hives that last more than six weeks without an obvious cause (such as an allergy), talk to your doctor about getting tested for autoimmune disorders.

Cause of Hives

Hives are a skin rash that usually appears as small red spots on the skin. It can also be accompanied by itching and swelling. Hives are often caused by allergies, but other factors can also cause them.

The most common causes of hives include:

• Foods, such as eggs and peanuts
• Medications like penicillin or cimetidine
• Insect bites or stings, such as from bees or mosquitoes
• Allergic reactions to pollen or other environmental factors

Other possible triggers for hives include:

• Stress,
• Infections such as colds or flu,
• Exercise and heat exposure,
• Pregnancy (especially during the 3rd trimester),
• Certain types of cancer chemotherapy drugs (such as chemotherapy drugs used for the treatment of Hodgkin’s disease).

If you have hives:

• Avoid scratching them because this may lead to infection or bleeding under the skin.

• Use cool compresses on the affected area to help relieve itching and inflammation.

• Use over-the-counter antihistamines to help relieve itching and inflammation (ask your doctor before taking these medications).
