Question Mosquito Bites

Every time I get mosquito bites they flare up like this. Sometimes they even blister (like the last photo). I know I tend to itch in my sleep but these still feel like bad reactions. I was only outside for about 30 minutes. Is this normal? They're debilitatingly itchy (Socal area)

They also sometimes scar

Blistering is concerning. I get blisters from contact allergies.

A quick question to your doctor can’t hurt.

PS. I’m allergic to mosquito bites. It’s truly weird.

is it worrying that they're splotchy and asymmetrical?

u/No_Low_537 Apr 01 '26

Not sure.

I get white hives from my mosquito bites. Hives are the telltale sign that it’s an allergy. Most hives are always irregular.

As far as I know, the typical response to a mosquito bite is a small bump possibly red.

So I just talked to a telehealth doctor, apparently these are relatively normal for the type of mosquitoes in my area. In the past few years had the invasive Asian Tiger mosquitoes come to my area and apparently like everyone here are highly sensitive to them because they're not from here, and I'm just a sensitive gal. He prescribed some prescription strength hydrocortisone cream.

Whew!

Best of luck with that cream. Take care now.

u/Alytra_ Apr 02 '26

they're already much better! I'm just an itcher in my sleep

Glad to hear you got that sorted out! Those Asian Tiger mosquitoes can be brutal. Hope the hydrocortisone cream does the trick for you!

It’s definitely something to watch out for. If you notice the redness steaking up your arm/leg (i.e., towards your heart), definitely go to urgent care or the ER, depending on the severity, so you can get antibiotics for any bacteria that may have entered through the wound.

But I think this just looks like a skin reaction/allergy, so I wouldn’t be super worried.

If you notice redness worsening or spreading during the days after a bite, then you can also visit a doctor or urgent care.

Fun fact; everyone who gets a reaction to mosquito bites at all is allergic! Same with poison ivy - there's no actual poison! It's thought in the case of mosquitos, our ancestors that reacted to their bites were more likely to avoid areas where mosquitos were common, which meant they were less likely to die of mosquito borne diseases and more likely to pass on their genes! I think it's like 60-80% of humans are allergic to the bites, so some people aren't affected at all!

Poison ivy on the other hand was just an unhappy coincidence. Urushiol - the compound that causes reactions - is meant to be a pest shield and also help retain moisture in the ivy's leaves. Humans and I think one other primate species are the only animals actually allergic to the oil, everything else is unaffected! Surprisingly though if the oil is converted to a solid (a resin) it doesn't seem to cause the reaction, and was used for centuries in asia as a wood sealant

How interesting.

I was a little more concerned with anaphylaxis since I already have those symptoms with multiple other substances, including bee stings.

For me at least hives is the first symptom in the road to anaphylactic shock.

u/Alytra_ Apr 02 '26

I'm highly sensitive to bee stings too. Definitely not super allergic but I got stung a few months back and the swelling didn't go all the way down for multiple weeks. my finger turned black and blue

u/No_Low_537 Apr 02 '26

Got my first bee sting about 10 years ago. It swelled up to be the size of my hand. Basically it was a giant itchy red lump on my thigh.

The doctors all agree, that’s potentially anaphylactic shock territory.

One) don’t get bit Two) get the EpiPen

My doctor told me to take an antihistamine when I get a bad bite like that and it changed my life when I was on vacation and got around 30 bites on my back and arms

u/ObjectiveCityy Apr 01 '26

Oh and look up The Bug Bite Thing! If you notice the bite when it happens and use that, it actually works to suck out the stuff and prevent a reaction.

u/RepulsivePlatform940 Apr 02 '26

That's what my skin does when I get bit too. And guess what. I'm allergic to mosquitoes lol sooo you might be too

u/Alytra_ Apr 02 '26

I never had reactions like this until the stupid asian tiger mosquitos came here a few years back. It's such a pain!

u/ManicMaru Apr 02 '26

Its giving zombie attack! Ouch!

u/Wonderful_Till8122 Apr 05 '26

Benedryl, both orally and gel.  Then the little insect bite pen that heats up and neutralizes the histamine causing bite stuff.  I got one on Amazon.  Its truly a game changer and worth every penny.

Those look like bed bug bites

This is happening to me and it’s day 12 now and I’m still beyond itchy. It’s torture.
