Exercise induced allergic reaction

[Orangelover]

Right Mumsnet am I going crazy or is this a possibility?

I've never been an exercise freak, but try to go to a class or two a week just to try and keep the flab at bay because I'm partial to nice food and the odd drink here and there. I mainly do spin classes or something like Zumba.

On the odd occasion I've pushed the intensity a bit, and done something like a run on the treadmill and maybe got a bit hotter and sweatier than usual I sometimes go all blotchy and break out in a kind of hives situation

There has been two occasions recently, one including this afternoon where following a run I've literally come out in a rash, had to dash to the loo and I swear today my tounge was actually tingling, no swelling though. Genuinely felt rough for a good hour or so afterwards and have taken an anti-histamine. I'm starting to actually panic I've got some sort of allergy to higher intensity exercise Google tells me it's possible but extremely rare.

Has anyone ever heard of this? It's really put me off exercising if I'm honest! Will obviously be cautious and making a Drs appointment but am I going mad?

What foods contain histamine @kingsleysbootlicker ?

@Thethingswedoforlove A lot of them, unfortunately! This is a good basic guide that includes a list of foods to try to avoid. It's quite a complicated thing to manage as consideration also needs to be given to food prep/cooking/storage, and other things can cause high histamine like medications, environmental issues. But as a start, changing diet can sometimes be enough to at least confirm that histamine is an issue

That’s incredible.

I have had this exact thing after having a random reaction to oat milk I think. I tried to exercise and I have the worst feeling in my throat. I have downed some anti histamines (I take them daily) plus my asthma pump. I now feel really sick

Another one here with exercise- induced anaphylaxis. I haven't worked out my trigger, but it tends to happen if I've taken a break from exercise and then start again, and only for the first week or so. Its particularly bad for me with running or fast walking which I do outdoors so I wonder now if it could be grass or pollen as I do have those allergies.

I felt ridiculous saying to my immunologist that I thought I was allergic to exercise, but yes apparently I am.

I find antihistamines help if taken before.

Look up cholinergic urticaria
I was diagnosed age 12 and I've been on every diet and antihistamine that exists
Finally got approved for Xolair and it's been an absolute game changer
This is without it - I can't wear a coat, change temperature, clean, Hoover, have a hot bath or walk let alone exercise. The hives are head to toe and even on the palms of my hands and itch like crazy

I have exercise induced anaphylaxis. For me it seems to be connected to eating wheat before exercising. I ended up being rushed to resus under blues and twos when I had a four week old baby when I collapsed.

Definitely get to the GP and get checked out. Get a referral to an allergy clinic.

I manage mine by not eating before any significant exercise, I take a slow release antihistamine daily and carry Piritin and an Epipen just in case but have always managed to knock back any reactions with the Piriton so no more A&E visits since.
