Dr. Zakia Dimassi Pediatrics
This condition is known as hives, or urticaria, can occur as a result of a number of triggers, and leads to swollen itchy skin in multiple areas of the body.

For acute (duration less
than 6 weeks) urticaria, the main possible precipitating agents are:



·        
Recent illness



·        
Medication use



·        
IV radiocontrast media



·        
Travel



·        
Foods



·        
New perfumes, hair dyes,
detergents, lotions, creams, or clothes



·        
Exposure to new pets
(dander), dust, mold, chemicals, or plants



·        
Contact with nickel,
rubber, latex, industrial chemicals, and nail polish



·        
Sun or cold exposure



·        
Exercise



·        
Alcohol ingestion



 Symptoms of urticaria can last from
minutes to months - or even years, in case it becomes chronic, but it is
usually a self-limited condition.



Urticaria has the appearance of large bug bites that are
characterized by the following:



They
can appear on any area of the body; their shape may change and jump from one area to another, disappear and reappear over short periods of time.



The
bumps - red or skin-colored “wheals” with clear edges - usually appear suddenly
and go away just as quickly.



Pressing
the center of a red hive makes it turn white - a process called “blanching.”



Even with treatment, this
rash may still persist for a few days before it resolves.
