This depends on how your body reacts to the bite, which is difficult to predict. Most responses will be mild, with only a few symptoms that resolve after a few days.Minor reactionsA minor allergic reaction will only occur around the insect bite area. Symptoms can include:SwellingRednessSome painItchinessWith a minor reaction, you’ll still feel like yourself but might find some irritation where the insect bit you. The symptoms of a mild response should disappear after about a week.Local allergic reactionsA local allergic reaction will also stay around the insect bite area. For example, if you have an insect bite on your finger, you might get symptoms on your hand and your arm, but they won’t spread further than this.The symptoms of a local allergic reaction include:Urticaria (hives)Redness or swellingWatery eyesRunny noseSneezingIntense itchingLocal allergic reactions can be treated with over-the-counter medication. Symptoms should reduce after about a week, even if they still feel slightly uncomfortable.Systemic allergic reactionA systemic allergic reaction will spread to other parts of your body. You might still get rashes, urticaria or itching at the insect bite site, but you may also feel generally unwell.Symptoms of a systemic allergic reaction include:NauseaTummy acheWheezingIf you have asthma, your asthma symptoms may flare up with an allergic reaction.

An insect bite or sting releases chemicals into your bloodstream, starting a chain reaction in your immune system.This chain reaction can cause symptoms like inflammation, swelling or itchiness. These symptoms mean your body is working on getting rid of the harmful substance. A severe allergic reaction means your immune system is sensitive to that allergen and overreacting to its presence in your blood.Medication can help you manage the symptoms as your immune system gradually eliminates the allergen.Types of insect bites and stingsNot all insect bites and stings will look the same. You can still manage the symptoms of an insect bite even if you don’t know what’s bitten you.You might be able to identify what insect bite you have by looking at the area on your skin.Bee, wasp and hornet stingsBee, wasp and hornet stings feel like short, sharp scratches when they occur. The stings leave a visible mark on your skin which might start to itch immediately. The sting mark can also feel painful.The stinger might be left behind if you were stung by a bee. Remove the sting as soon as possible, but be careful not to pinch, as this can cause the venom to spread further into your body.Horsefly bitesA horsefly bite is usually more painful than other bites. The bite can cause the skin to become raised and red. The size may also be more significant than other insect bites. Horsefly bites can take longer to heal compared to other insect bites.Midge or gnat bitesMidge or gnat bites can cause small, itchy blisters to form across your skin. These blisters might be filled with fluid. Avoid popping the blisters, as this can leave them more open to infection.Treatment for insect bites and stingsYou can take some steps immediately after an insect bite to keep your symptoms mild:Apply an ice pack or a cold compress to the affected area for 5 to 10 minutesRaise the affected areaRinse the bite or sting with fresh waterIf a stinger is stuck on your skin, remove it carefully without pinching.Over-the-counter products can help with the symptoms of an insect bite.
