Not to scare you but any thing that affects breathing is a sign of anaphylaxis
Which can resolve on its own or progress to anaphylactic shock (shutting down organs and death)
Symptoms
Anaphylaxis symptoms occur suddenly and can progress quickly. The early symptoms may be mild, such as a runny nose, a skin rash or a "strange feeling." These symptoms can quickly lead to more serious problems, including:
Trouble breathing
Hives or swelling
Tightness of the throat
Hoarse voice
Nausea
Vomiting
Abdominal pain
Diarrhea
Dizziness
Fainting
Low blood pressure
Rapid heart beat
Feeling of doom
Cardiac arrest
People who have had a severe allergic reaction are at risk for future reactions. Even if your first reaction is mild, future reactions might be more severe. That's why it's important to carry self-injectable epinephrine if you are at risk, and 911 should be dialed in the event of a very serious reaction.
Understanding anaphylaxis and the things that can trigger this severe allergic reaction will help you manage your condition.

Anything that involves two systems requires the administration of an epi pen for ds and calling 9-1-1
Food allergy action plan (also applies to drugs /stinging insects for ds )

Please request a consult with an allergist asap
Past reactions are not predictive of future reaction
Benadryl does not stop anaphylaxis
It will stop itching and rashes
But not breathing issues or throat swelling or blood pressure drops etc....
Think of Benadryl as the stewardess on a plane crash
They make the passengers feel slightly better but can't stop the plane crash
The epi pen is the pilot - if it's acted upon early enough then there's a better chance of stopping the crash
Ds is allergic to multiple drugs
His allergist will not permit Ds to take meds that he has signs of an allergic reaction to
The only exception to this is contrast dye for an MRE
On which case Ds has to be hospitalized and given Iv syeriods multiple time for 24 hours before and monitored very closely
Please talk to an allergist about your sons reactions
