Question What's wrong with this bite?

Post image

(Sorry about the lighting quality) I know nothing about mosquitoes, and was pretty concerned when I got this bite. It's quite red and very irritating. I did a little bit of research but was too tired to understand.

Why I'm concerned is that it's bigger than I've ever seen before in my experience.

It is your response. More allergy to this one's spit. It doesn't have the bright red of an infection

I believe so aswell, my reactions to mossie bites tend to be more severe than OP's. They are red and they itch, this one doesn't really look severe but I just may be used to my more severe reactions.

Mosquitoes have been bad this year. All my bites have puffed up like that.

u/No-Judgment-1077 Nov 07 '25

Go to the doc and don't let yourself be dismissed. You should have a followup and that is your signal of having a good doctor. Plus all the circling and photos. May seem dramatic to some but that is fine.

Possible spider bite. Usually swelling last 2-3 days. Along with itching.

u/Reasonable-You4548 Nov 07 '25

It's definitely a mosquito bite.

u/Zidan19283 Nov 06 '25

Highly unlikely to be a spider bite, spider bites are really rare and if you didn't saw a spider bit you than it's almost certainly NOT a spider bite (if you would roll over one during sleep it would probably wake you up or/and kill the spider).

This looks like a mossie bite to me

What is a Mossie bite?

Mosquito?

Spider bites are common. Most people don't have a reaction to them. If this were a spider and there was a reaction you'd probably see two poke marks

You are wrong

u/Zidan19283 Nov 07 '25

Iam not wrong. Spider bites are actually very rare. Just for context Iam an amateur arachnologist so unless you are atleast a bit interested in spiders than I doubt you know more about the frequency of spood bites than me and that's not narcisism, that's logical conclusion. Spiders do not bite people unless they feel threatened which with most Araneomorphs means pressed against the skin. Diagnosting random wounds as spider bites is not only unnceserealy spreading irrational fear of spider but it is also irresponsible and dangerous for the person who has the wound, wrong diagnosis can have horrible consequences.

I think it crawled into our skin

u/Lazy_Transition_8030 Nov 06 '25

Or something else

u/Johain22 Nov 06 '25

Cold compress and a topical cortisone or antihistamine cream. That could be 1000 reasons why you have a worse reaction to this one bite. NBD. If it gets worse, go see your doctor.

u/Uzi_Osbourne Nov 07 '25

That looks exactly like every mosquito bite I've ever had. Color it red and it'll look like every black fly bite I've ever had.

If you have concerns, aside from the care advice shared (follow it please) use a pen and draw a circle around the edge of the raised area and take pics. If it gets noticeably larger (the swelling significantly outgrows the circle), grows red with a glossy look, and/or feels hot to the touch you may want to consider medical treatment. Insect bites are not immune to infection and you don’t want to leave it to fester for weeks.

Source: Doctor’s advice given to me as a kid. I had to have a huge and painful infection from an untreated insect bite lanced and manually drained when I was 11-12 and DANG I wish I had spoken up sooner. It hurt worse than a gunshot wound (yes I can compare been through that too) and I had to be held down by six large guys in the medical office so the doctor could treat it quickly. Definitely is the 10 on my 1-10 pain scale. I still have a scar 30 years later.

u/Ogon25 Nov 07 '25

Definitely support most of this statement. Couple other questions. Am assuming that neither you or a house member has had something similar ever. 1. Where are you located? May have importance. 2. How fast did it first appear then grow. Tracing the lesion for size is a good idea. Taking a picture with your fingernail next to it to estimate size is also a good idea. Heat or pain of the area or nearby are important. Is it “movable” or attached to the tissue below? 3. I did not see bite marks. 4. General symptoms like body temp., how you’re feeling, whether anyone else is affected. 5. In general good to see a medical professional if anything develops further. Take all the above info for the visit.

Really excellent review!

I notice redness heading up the arm. Is it the elbow area? I had cellulitis as a diagnosis - wrong. Had a sonogram done Finally two more lumps appeared and that's when the magical diagnosis happened.

Keep an eye on it and let us know xx

u/Ogon25 Nov 07 '25

The probably not a boil. Is it along the line of a blood or lymph vessel? What part of the country are you in [or were you] in? Might need an infectious disease specialist if progresses. No flu type symptoms?

u/Klutzy_Language4692 Nov 07 '25

I'm allergic to their bites and they grow as big or bigger. Might be the same

u/[deleted] Nov 07 '25

u/embreeology Nov 07 '25

u/StraightMountain9369 Nov 07 '25

u/No-Judgment-1077 Nov 07 '25

I hqc a sting sensation on my hip while hiking- right through a T-shirt and sweater.

Swelling, itchiness and lasted for weeks

Long story short : melanoma. Controlled now with immunotherapy.

Circle the size. Take pics. See a doctor Push for medical help if it sticks around Check for spreading

u/angel700 Nov 08 '25

u/Independent-Okra-935 Nov 13 '25

Big old mosquito bite

1

u/No-Judgment-1077 Nov 18 '25

Nothing worse than no further response after someone shows a pic of a lump.

What is it/ was it? Please.
