Sometimes the body releases too much histamine. The result is mosquito bite swelling, or what's called a “wheal.” The area around the bite rises, turns red and begins to itch. How much and for how long varies from person to person, but swollen mosquito bites generally are about the size of a dime and last about a day. Doctors at the Mayo Clinic report that, in some people with extreme sensitivities, mosquito bites can swell to the size of grapefruits and linger for days.

Best Answer: Sea Breeze helps the itch to stop, if you have that. If you don't scratch the bites and you are not very allergic, they will go away within a few days. If you're highly allergic, even if you don't scratch them it could take weeks. If you scratch them, they won't go away for weeks and weeks - not until you stop scratching them, at any rate. If you're highly allergic, though, and you scratch them a lot, you could be looking at a hospital visit during the next three weeks. Source(s):

A symptom is something the patient feels and reports, while a sign is something other people, such as the doctor detect. For example, pain may be a symptom while a rash may be a sign. In most cases insect bites cause a small itchy lump to develop on the skin. Sometimes the bite itself may be visible (a tiny hole). The lump may be filled with fluid.

Horsefly bites may take a long time to heal. This is because the insect cuts into the skin when it bites. Bedbugs - initial bedbug bites do not generally present any signs or symptoms. However, sensitized individuals (sensitivity increases after subsequent bites) may develop weals or papules.
