In brief: Anaphylaxis
The relative timeframe for anaphylaxis to occur after exposure to a particular allergen or antigen can vary from seconds to hours.
It could take from 30 minutes to an hour before the problem develops. As a general rule, the sooner the symptoms of anaphylaxis appear after exposure then the more severe the reaction is likely to be. Those symptoms relating to the surface of the skin may be the first.

In brief: Anaphylaxis
Anaphylaxis may occur within sec to min.
After bee sting and is usually rapid and life threatening. A bee sting may initially not cause a reaction. It may be the subsequent sting that provokes a response. It is actually statistically rare to have a an anaphylactic reaction to bee stings after an uneventful 1st event. No specific tests can predict evernts. Conservatively-an Epipen (epinephrine) may be kept.
