I am a 31-year-old woman. Why do I have chronic itchy welts?

Question

Hello doctor,

I am a 31-year-old woman who has been breaking out in raised, itchy red welts all over my body for the past four months, and I cannot figure out what’s causing them. The hives appear suddenly; sometimes I wake up covered in them, or they develop within hours after eating or being exposed to something. They are extremely itchy and can appear anywhere on my body: arms, legs, back, face, and even my scalp.

The welts vary in size, from small bumps to large patches, and they often join together to form bigger raised areas. What’s frustrating is that they seem to move around; warts will fade in one area and then pop up somewhere else within hours. I’ve been trying to identify triggers, but it all seems so random. Sometimes it happens after eating shellfish or taking ibuprofen, other times after exercising or being in the sun. And sometimes, there’s no obvious trigger at all.

The itching is so intense that I scratch until I bleed, and it’s starting to affect my sleep and daily life. Could this be chronic hives (chronic urticaria)? And why can’t I pinpoint what’s causing them? Is there a connection between my stress levels, certain foods or medications, and these unpredictable breakouts?

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

The symptoms you are describing, recurrent, itchy red welts that appear suddenly, move around the body, and have lasted for more than six weeks, strongly suggest a condition called chronic urticaria (chronic hives).

In many cases, chronic urticaria is considered idiopathic, meaning no clear external trigger can be identified. However, certain factors such as specific foods (especially shellfish and nuts), medications (like ibuprofen or antibiotics), heat, pressure, sunlight, or even stress can contribute to flare-ups. The fact that your hives seem to come and go, appear in different areas, and worsen with physical activity, sun exposure, or specific foods fits this pattern well.

There is a well-established link between stress and chronic hives, as stress can activate immune responses that increase inflammation and trigger histamine release, even in the absence of a known allergen. Additionally, autoimmune processes may be involved, where the immune system mistakenly activates mast cells and causes histamine release without any external cause.

Although it can be frustrating not to pinpoint a single trigger, effective treatments are available. The mainstay of therapy includes daily non-sedating antihistamines such as

Cetirizine.
Loratadine.
Fexofenadine.

These may be prescribed at higher-than-standard doses under medical supervision. If symptoms persist, a doctor may also recommend:

Montelukast (a leukotriene receptor antagonist).
H2 blockers (like Ranitidine or Famotidine).
Omalizumab (a biologic therapy for severe, treatment-resistant cases).

Keeping a symptom diary can help identify patterns and potential triggers. In addition, avoiding known aggravating factors and managing stress through relaxation techniques, mindfulness, or therapy can significantly reduce flare-ups and improve quality of life.
