Hives can appear anywhere on the body. These small red bumps or white, itchy patches called wheals may show up close to the site of the allergy attack or across the entire body as a result of shingles or other skin conditions. You may be surprised that so many different things cause hives.

Hives on Legs

Hives on the legs are the result of an allergic reaction that causes your body to release histamines. Histamines cause blood vessels to become inflamed and leak fluid, causing itchy bumps that look like hives.

Most people who experience hives on their legs will never know what caused them because they happen for no apparent reason.

However, there are some common causes of hives on the legs:

1. Food allergy

If you have a food allergy, you may develop hives on your legs after eating the food that triggers your allergy. Common foods that can cause hives to include peanuts, shellfish and eggs.

2. Insect bites

Insect bites can also trigger hives on the legs and other parts of your body because they contain insect venom that triggers an allergic reaction in sensitive individuals.

3. Stress

Although stress is not considered a direct cause of hives, it can make symptoms worse if you already have an existing condition such as an allergy or asthma because stress affects immune function which makes it harder for your body to fight off these conditions when they arise.

4. Allergies

The most common cause of hives is an allergic reaction to a substance you’re exposed to frequently, such as an insect bite of food you eat regularly. These substances are called allergens.

5. Infections

Infections such as strep throat or mononucleosis can also sometimes trigger hives. This is because infections can cause your immune system to release chemicals that trigger inflammation which is what happens when you have hives.
