Why do I have Hives on my Legs?

Have you ever seen someone scratching their leg, and got confused as to why they were doing that? Maybe you thought it was just a funny tick or something. But then you noticed they have constantly scratched legs. You may be wondering, why do these people have hives on their legs?

Ever get hives on your legs? It’s not fun, I know. As I was researching hives on the internet, I still couldn’t find a clear explanation of why they occur, other than they are harmless. That’s it. No causes are revealed. Some sites just say to take an antihistamine and all will be fine. And while that generally works, there is no explanation of why histamine is suddenly released, nor what triggers its release.

Here’s the deal. You’re probably wondering, “Why do I have hives on my legs?” or, “What does this mean?” or, “What do I do now?”


First of all, we want you to know that you’re not alone. Hives are incredibly common and affect millions of people every year. The good news is that hives are usually not serious and don’t cause any problems for most people who have them they just look weird and can be a little uncomfortable!

It’s important to understand what hives are so that we can help you figure out what might have caused yours and how to treat them if they’re bothering you.

Hives on the Legs

Hives are small, raised, red bumps that quickly develop when your body is exposed to an allergen. They can be itchy and uncomfortable, but they aren’t dangerous on their own.

Hives on the legs are common in adults and children over 6 months old who have allergies, especially pollen allergies. You may also have a food allergy if you have hives on your legs that come and go during certain seasons of the year and disappear when you avoid eating certain foods or drinking milk products or juices that contain them.

Some people who have hives on their legs only get them when they exercise vigorously or spend time in hot weather. This is known as exercise-induced urticaria (EIU). It’s thought that sweating causes fluid loss from the body, leading to dehydration which triggers the release of histamine and other chemicals

What causes hives?

Hives are a condition where you get itchy, red welts (also called urticaria) on the skin. Hives can affect any part of your body but are most common on the arms, legs, and trunk. They don’t hurt and they don’t last long usually less than 24 hours. But they can be very annoying because they make your skin feel like it’s burning or itching.

Hives can be caused by many things, including:

• Allergies (like food allergies)

• Stress

• Weather

• Medicines (like antibiotics or hormones)

• Infections with viruses or parasites (like scabies)

• Autoimmune diseases like lupus or rheumatoid arthritis
