I have just returned from corfu. I had mosquito bites, not itchy little red dots. Now I started with white lumps, itchy, now red, delayed reaction? Tia

It's possible. ..: ...but I think you first have to question whether the "itchy little red dots" were actually mosquito bites. Other kinds of bug bites, heat rash (miliaria) or even swimmer's itch caused by an allergic reaction to a waterborne parasite can produce red or white bumps. Use OTC cortisone cream for a day or two. If rash is progressing/not improving, seek medical eval. Good wishes:)

What does a allergic reaction of a mosquito bite look like?

Depends: If your talking about the mosquito getting a rash after he bites you its hard to see. Look through a magnifying glass at his chest and proboscus area. Usually they fly away before you can find a tiny magnifying glass. As for the situation of a rash on you from the mosquito. It looks red, bumpy and is itchy.

When feeling itchy from a mosquito bite means you were just bitten, or the bump reaction takes 2-14 days to appear? Can't tell when I'm getting bit

When feeling itchy from a mosquito bite means you were just bitten, or the bump reaction takes 2-14 days to appear? Can't tell when I'm getting bit

Usually just bitten: A person can notice a mosquito bite right away, or within a few minutes. If she is asleep, it may take longer to notice. If bitten while sleeping, she should notice the bite upon waking up. A new mosquito bite should be visibly growing in size on the skin surface during the first couple of hours.

Dark patch of skin left on mosquito bite areas >2 months after allergic reaction to mosquito bite was over. Never had this before?

Post inflammatory: Post inflammatory hyperpigmentation is a common and normal response during the healing process. When traumatized skin heals, redness, followed by dark discoloration often occurs. With time, the site will usually resume normal coloration to match the surrounding skin. Topical steroid creams applied initially can help reduce inflammation and prevent excessive discoloration.

My child has a bad reaction to mosquito bites. Is he allergic?

My child has a bad reaction to mosquito bites. Is he allergic?

Probably.: Allergy to proteins in mosquito saliva is common but immunotherapy (allergy injections) is neither effective nor necessary. With continued exposure almost everyone develops tolerance to mosquitoes in their locale. When they go elsewhere they're bitten by other mosquitoes & often reactions reappear. This is why mosquitoes only seem to bite tourists & not natives. All are bitten; only newbies notice.

Woke up w/ about 20 (mosquito) bites in mexico, varying sizes up to a few 2" welts. Allergic reaction? What 2 do?

Yes, reaction: 2 inch welts x 20 can be very uncomfortable. Cool packs and benadry (diphendydramine) can help. I've also seen baking soda help. Watch for signs of infection.

Have mosquito bite. More red than yesterday & itchy & feels warm to the touch. Not any bigger. Is red/itch/warmth a normal reaction? Worry about infection

Have mosquito bite. More red than yesterday & itchy & feels warm to the touch. Not any bigger. Is red/itch/warmth a normal reaction? Worry about infection

Normal: The mosquito secretes saliva that you are reacting to. So it's normally red. Keep the area dry and clean. If it begins itching, you can try using calamine lotion. You don't need to worry about infection, unless you see pus developing. Usually this doesn't happen.

A mosquito bite resulted in an allergic reaction of 4" red bump with 3" darkred center that's turning purple. Is that normal for an allergic reaction?

A mosquito bite resulted in an allergic reaction of 4" red bump with 3" darkred center that's turning purple. Is that normal for an allergic reaction?

That sounds like: A localized allergic reaction. No, most- people don't have that significant of a reaction. The mosquito's saliva contains a substance that effects clotting - which is why the lesion is purple.

Mosquito bite 3 days ago. Bruising present; never had reaction before. Headaches and diarrhea followed. Consistent for 3 days now.?

Mosquito bite 3 days ago. Bruising present; never had reaction before. Headaches and diarrhea followed. Consistent for 3 days now.?

Just a thought: But the appearance of the bite (eg bruising) is NOT typical of a mosquito bite and Springfield Mass NOT a place with any REPORTED mosquito borne illness thus far this season (I am in Massachusetts) Sounds more like a SPIDER Bite with a reaction to the toxin. ....some pretty "powerful" spiders exist in Western MA. Hope this helps See ILLUSTRATION DRZ

Am I having an allergic reaction to mosquito bites? What do I do? Its itchy, looks puffy but not too swollen, looks like a burn. Benadril doesn't help

Am I having an allergic reaction to mosquito bites? What do I do? Its itchy, looks puffy but not too swollen, looks like a burn. Benadril doesn't help

Allergic 2 mosquito?: Some have large local reactions to mosquito bites. Try soaking in cool water bath with domeboro's powder (follow box-directions), then apply an otc Hydrocortisone preparation (usually 0.5 - 1%). If no change after 1-2 days, go see a doctor. Benadryl (diphenhydramine) only helps the itch.

2yr old with 102.5 fever stomach pain no other symptoms. Had an allergic reaction with hives 1 1/2 weeks ago for excessive mosquito bites.

Fever: Your child may have a viral illness and in fact may be incubating roseola which is a benign virus affecting children under two years, whereby the fever lasts for three days, the fever breaks and the child breaks out in a rash. I doubt that the fever is connected to the mosquito bite.
