Your health professional will ask you several questions to determine whether you could be having an allergic reaction to an insect sting. Questions may include the following:
You may be asked to capture or kill the insect and bring it in for identification.
You may be asked about previous stings and what reactions (if any) you may have had. Your doctor will also try to determine whether you have any medical conditions that might affect your risk of future allergic reactions or your choice of treatments for the allergy.
