Possible to get fever from allergies?

No fever from the allergies to nature and growing things. There is a really high pollen count now. I live in the country and I see all the cars are covered with yellow pollen.

If you were running a temp, you had flu.

Glad that you are feeling better. Stuffy runny nose will calm down in a day or so.

It’s a cold. Flu does not have congestion. Flu also typically has high fever, like 103+, but everyone is different with how their body reacts.

I have developed sinus infections and bronchitis from allergies. It isn’t that the allergies caused the infections. It was that the post nasal drip and congestion, left untreated, turned into these ailments, which, btw, are accompanied with a fever.

Severe allergies can compromise your immune system.

It’s true it could be a secondary infection to an allergy. But, not likely since it all happened within 12 hours from what you described.

It depends on the allergy and how reactive a person is. Peanut allergies for instance. Many people just get itchy, but others can go into full blown anaphylactic shock or respiratory arrest. It may also be that the allergy just lowered your immune system enough that you picked up a bug that otherwise wouldn’t bother you.

The body’s stock response to unwanted invaders is inflammation—which both allergies and fever are, basically. Since allergic responses can range anywhere from kind of bothersome to life-threatening, feverishness could certainly be one possible response.

Secondary infection. Thanks, @JLeslie. I couldn’t come up with the correct terminology.

@bkcunningham Sure. You made a good point.

Although, I never understand why people prefer to think they have an allergy rather than a cold. I’m not saying you are like that, but this Q just reminds me of it. My MIL is like that. She always says she has an allergy or her grandchildren, and then within 48 hours someone else has the allergy. LOL.

I’ve taken a combination of prescription allergy medicine for more than 25 years. I had to take it twice a day. I can’t take it now because the combination of steroids has caused early onset cataracts. Ugh. Thus, the sinus infections and bronchitis I’m glad I stopped smoking. I would have been hospitalized this year my allergies flair ups were so severe.

@bkcunningham My father did the shots for dust allergy. He constantly is plagued with drainage and sinus infections. The allergies add to, or start the suffering. When he needed heart bypass they delayed a week because of his sinuses. When he went in they were going to delay again, and he said, “I’ll be like this for months.” It’s worse for him during the winter months. They did the surgery, he was fine.

I didn’t mean people who are long term seasonal and indoor allergy sufferers. I mean people who don’t have allergies generally who get sick for 3–7 days and think it is an allergy. I think it rarely is, but there are those rare occasions.
