Onset of anaphylaxis unknown allergen

[Aurorie11]

Looking for advice having spent 5 hours in A&E today.

Background, early 50s F minor allergy issues hay-fever for 40 yrs plus, bit of a reaction to a wasp sting couple of years ago but dealt with at home with antihistamines.

Yesterday woke with puffy face and neck both sides, no issues breathing etc. Went to pharmacy and given alternative antihistamines.

This morning at 5.30 eyes didn't feel right when looked in mirror welts under them took new antihistamine then. Made a cup of tea antihistamine had no impact and rash spread to neck/upper chest and upper back. Phoned 111 for advice who wanted to send an ambulance but I declined and drive myself to A&E.

Had adrenaline and IV antihistamines and hydrocortisone. Bloods taken, no issues there.

Discharged with 5 days of steroids and 3 days of antihistamines.

No idea what triggered this, racking brain to think of anything different to eat or new products used, but struggling to identify anything.

Doc at A&E recommended getting appointment with allergy clinic specialist, phoned GP and got GP appointment in about two weeks to ask for a referral.

Looking for advice/experiences please

Glad they are being thorough now. I had never realised new reactions could develop until one of the students at my school had a massive reaction to something he had previously eaten with no issues.

Might have a guess on what set this off, just been through all the products I use. Found a cleanser I've been using recently it contains fig, we have a fig plant in the garden we inherited with the house and the sap causes a rash.
The reaction started on my face so cleanser is top of my list of suspects. But have a box full of products for DH to store in garage and others I'm throwing from the same brand as the cleanser. Keeping the suspect product for when I see an allergy specialist

@Aurorie11 did u manage to find out whag caused it ? Did anything help! X
