Question 1

My whole body stings when I exercise or take a hot bath (cholinergic urticaria).

Accepted Answer

This is cholinergic urticaria that occurs when body temperature rises. Characterized by small wheals and intense stinging, it is closely related to sweat excretion dysfunction.

Question 2

Along with hives, my lips or eyes swell up (angioedema).

Accepted Answer

This is angioedema that swells in the deep layers of skin. If the inside of the throat (airway) swells, breathing difficulty can occur and emergency treatment may be needed immediately.

Question 3

I get hives when I exercise after eating wheat.

Accepted Answer

This is food-dependent exercise-induced hypersensitivity that only occurs when exercising after eating certain foods. Exercise after food is fully digested or avoid the trigger food.

Question 4

I scratch compulsively when stressed — is this a habit? (psychogenic)

Accepted Answer

This is not a habit but psychogenic itch felt in the brain. Stress hormones stimulate nerves, and treatment to manage the mind should be combined.

Question 5

My skin swells in the shape of scratches (dermatographism).

Accepted Answer

This is dermatographism that reacts to physical stimulation. About 5% of the population experiences it, with swelling and itching where tight clothing or watch straps press.

Question 6

I have been taking antihistamines for over 6 months but they only work temporarily.

Accepted Answer

This is chronic urticaria that returns when the medication wears off. Rather than simply suppressing histamine, detox treatment to stabilize the over-sensitized immune system is needed.

Question 7

There is nothing on my skin but my whole body is maddeningly itchy (pruritus).

Accepted Answer

Pruritus without rash can be a signal of systemic diseases such as dry skin, anemia, diabetes, or thyroid disease.

Question 8

I get hives when exposed to cold wind or air conditioning (cold urticaria).

Accepted Answer

This is cold urticaria that occurs when exposed to cold. The skin temperature regulation ability has declined; keeping warm and raising basal body temperature is needed.

Question 9

As I age, my whole body itches and skin flakes (senile pruritus).

Accepted Answer

This is senile pruritus caused by decreased skin lipid film and drying of fluids. Avoid frequent bathing and high-moisture care with fluid supplementation is needed.

Question 10

I have a fever with hives — should I go to the emergency room?

Accepted Answer

It may be a sign of infection or systemic disease, not simple hives. If accompanied by high fever (38 degrees or above), immediate medical attention is needed.
