Why did my mosquito bite turn into a hard lump under the skin on the top of my leg?

Not sure: An extreme allergic response could cause a large welt, and it could last a couple of days. If this is very old, though, it is possible it wasn't a mosquito but some other insect and it left a stinger inside you. If painful, it could be infected. You might want to have it examined to see if there is pus that needs to be released. Meanwhile, apply warm compresses for 15 mins 4x daily. ...Read more

Unusual: I do not expect a mosquito bite to be painful and wonder if your bite was from another bug such as spider. If it is still painful, see your doctor to make sure that the area has not been infected. ...Read more

After a week of Benadryl (diphenhydramine) for my swollen and red mosquito bites, a hard circular lump has formed under both bites. What can I do to get rid of them?

Cortisone cream: Best not to use topical Benadryl (diphenhydramine) as it is a potent sensitizer and many will develop an allergic reaction from it. Topical cortisone creams work best. The redness and lump should gradually fade.
Some insect bites persists for years and are called dermatofibromas. ...Read more

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:) ...Read more

Insect Bite...!!!: Dr. J. Ferguson advised warm compress, dr. N. Munmeh- cold; confusing?

Any insect bite clean with soap water, if itchy, bumpy: cold compress 1st few hours, hydrocortisone; can give oral benadryl: to reduce allergic response.

If after 1-2 days getting even bigger, deeper: warm compress; if not better in couple of days- see her pediatrician to rule out possible infection and treatment if needed. ...Read more

Ingrown hair?: It's possible it's an ingrown hair, especially if you shave down there at all, but even if you don't it could be. It could also theoretically be a small cyst. Both can be painful.

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.

Should I squeeze a mosquito bite if its hard and sore?
