I have that! Spray some Flonase on the site and it should give immediate relief. It will also go down in 1-3 days

Could you try flumist for her next year?

Allergic to eggs must be so hard to navigate! Though at this point I’m sure your family has plenty of eggless recipes in rotation

Have your doctor keep track of injection reactions for MCAS (Mast Cell Activation Syndrome). I have this with certain vaccines and injections as well as mosquito bites. It gets worse in time. Large welt, hot to touch, sometimes itchy and stays for a long time. Not always on the actual injection site but nearby. It’s a reaction (allergic reaction) to the histamine your body produces from the injection.

I get that reaction with a lot of vaccines. TDAP is the worst - I had a softball size welt. It was really hot and uncomfortable. My immune system is just really dramatic.

My son had this from shoulder to elbow, no other known allergies. We were told to switch to flu mist.

I’m a pharmacist and unfortunately that reaction is fairly common! I’d say unusual for it to last a whole month though. Potentially it could be due to the egg allergy, but flucelvax and flublok r both egg free 💉 as well

Flublok and Flucelvax are not made in eggs. Worth a try.

Hi! I have had this experience 2 years ago. No egg allergy. CVS thought it was “Shoulder bursitis.” I can DM you a photo of my red circular arm rashes if you want. It happened to both of my arms, where they injected me. One side Covid Booster, one side Flu. The marks/ rashes grew to be about the size of oranges, so pretty big circles. Apparently, it was because of the technique they used when injecting me, hence why it happened to both arms. It lasted maybe 3 weeks. I put anti-itch cream on it, advised by CVS.

My son had two allergic reactions to the flu shot. He had allergy testing, and it turned out to be one of the preservatives. Unfortunately, it’s used in all versions so he can’t get the flu shot.

I had that happen to me this year for the first time. I've been getting flu shots for forever and this is the first time, it lasted about 2 weeks. It was really red, swollen, and very warm to the touch but wasn't cellulitis. The only allergies I have are pineapple and sulfonamide antibiotics, and nobody else in my house had any kind of reaction it was very strange.

Happens to me and I’m 41. I did the same with the tdap. I’m assuming there is a preservative reaction I’m having but I don’t know what it is.

It’s going to trigger mcas. It’s actually a known thing they don’t tell you about. I no longer get things that aren’t absolutely necessary because of MCAS reactions that have happened in our family. It’s awful to live with mcas

My oldest had the same reaction 2 years ago - he’s not allergic to eggs. We didn’t get it last year bc he got the flu before he got the shot.

I’ve gotten a reaction before but it seems kind of random. My kid gets it too sometimes. Hot and itchy, Benadryl helped. That is a really long time though. Flumist may be a good option for her if she is that uncomfortable

Is this your daughter who had PANDAS? My son has PANDAS and has this same reaction to the flu shot. Huge red warm welt that seems to last forever.

You can get the flu shot without egg- specifically ask for this, it’s not uncommon but they might not have it in every office

AlesciaK :
They make a egg free injection as well. It’s called flublok. The nasal flu shot is a live vaccine and can potentially have more side effects

I'm a pharmacist. it's possible she just has an over reactive immune system and it's just a histamine reaction. if it's the egg allergy causing this, Flucelvax and Flublock are egg allergy friendly

Krissa :
You have to special request a flu shot without the egg, we have them available to us as healthcare workers but must be requested early for them to get enough

Rachel :
Perhaps give an antihistamine the morning before she gets the shot. That’s what I do for my kids’ allergy shots.
