For minor reactions to a bee sting, wash the area with soap and water, and for more severe reactions, apply ice and take an antihistamine, as stated by Mayo Clinic. With either reaction, avoid scratching the area, and it is always suggested that a hydrocortisone cream is applied directly to the area.
If a person has trouble breathing after a bee sting, anaphylactic shock may be taking place and it is critical to seek medical attention immediately. A medical team will most likely give the patient oxygen with albuterol and administer an adrenaline shot to reduce the allergic reaction. If the person is known to be allergic to bee stings and has an emergency epinephrine device, it should be administered right away, as noted by Mayo Clinic.
