Those itchy red bumps: what if your skin is trying to warn you?
Itchy patches for no reason… What’s going on?
Imagine: You’re going about your daily business and suddenly, pink or reddish spots appear on your skin, slightly raised, and they itch terribly. What doctors call hives looks like a nettle burn. Small, sometimes painful, itchy blisters appear. They can appear anywhere: on the arms, thighs, neck, back, and even the face. The strangest thing is that they appear in the morning and disappear by evening… or vice versa.
For many women, these unexpected rashes disrupt daily life and cause anxiety. The good news: In the vast majority of cases, hives are a temporary reaction: the immune system “triggers” itself in response to a specific trigger. The bad news: They tend to return and cause physical and mental discomfort.

What happens in the body: histamine, immunity and vascular reactions
Mast Cell Activation
In response to an irritant – food, drug, physical or emotional factor – mast cells release histamine and other inflammatory mediators.Histamine and blood vessels:
Histamine dilates small blood vessels and increases their permeability. Fluid seeps into the surrounding tissues, causing blisters to form.Irritation of nerve endings
. The swelling activates pain and itching receptors: these are unpleasant sensations.Rapid onset and spontaneous disappearance.
Blisters appear within minutes or hours and disappear just as quickly, but often recur: a “pendulum” reaction.
