Multiple stings can have much more severe consequences, such as anaphylaxis, a life-threatening allergic reaction that occurs in children who are hypersensitive to the venom.
Hypersensitive infants cry in response to new experiences that do not normally upset other babies; ordinary comforting measures, such as holding, rocking, feeding, or swaddling do not work and may even make the crying worse.
Some infants are hypersensitive to stimuli, and their crying will get worse if they receive any more than a minimum of comforting, such as parental holding or cuddling.
People with AD may be hypersensitive to irritants because they have abnormally low levels of interferon-gamma in their systems.
Some hypersensitive people have unique chemical reactions in the brain that cause them to respond much more strongly to stress.
