could urticaria be a dissability when diagnose as severe
Hi,
This is a condition called physical allergy where your body will respond to certain stimuli and elicit an allergic response.
Cholinergic urticaria is a subcategory of physical urticaria (aka hives) that is a skin rash brought on by a hypersensitive reaction to body heat. Symptoms follow any stimulus to sweat such as exercise (sometimes called exercise-induced urticaria), heat from the sun (which could also indicate solar urticaria), saunas, hot showers (reaction to water can also indicate water urticaria), spicy foods which may cause an increase in body temperature or even stress due to blushing or anger.
The affected area will often feel warm and can be extremely itchy or exhibit a burning sensation. Typically the rash occurs on the upper trunk and the arms but can appear on other parts of the body. The rash may be worse in areas where clothing restricts the skin's ability to cool itself such as hat brims, waist bands, tight collars, backpack straps, etc.
Cholinergic urticaria can be very difficult to treat. Since an attack can often be felt coming on, it can sometimes be halted by rapid cooling, such as applying cold water or an ice pack to the skin.
Drug treatment is typically in the form of antihistamines such as loratadine (Claritin), hydroxyzine, cetirizine.
