Insect bites and stings are very common and usually lead to swelling and redness in the affected area. In some cases, these bites can also cause allergic reactions in the body. Insect bites are usually defensive in which case they bite or sting in self-protection. When an insect bites, it may inject venom which contains certain proteins that can cause an allergic reaction. Insects such as bees, hornets, wasps and fire ants can cause severe reactions in the victim. Mosquitoes bite in order to feed themselves with blood so that they can lay their eggs. These bites are not serious, unless the individual suffers from an allergic reaction. Insects can also serve as the carriers for various illnesses and infections which spread when they bite or sting. Ticks feed on blood and can spread lyme disease in the course of doing so. Chigger bites usually lead to itching and swelling in the areas of the bites.
The manner in which an individual responds to an insect bite or sting differs. The most common symptoms of insect bites are swelling, itchiness, redness and pain. There may be a tiny rupture in the skin and the area could become infected if it is scratched excessively. If timely treatment is not provided, the infection could spread and lead to a condition called cellulitis. Allergic reactions to the bites can result in symptoms that extend beyond the area of the bite. This condition is known as anaphylaxis in which symptoms such as hives, breathlessness and wheezing occur. If left untreated, it could even prove to be fatal. It is important to determine the type of insect bite you have received, so that the appropriate treatment can be administered and further complications can be prevented.
Once you have received an insect bite, you need to check first if it is a sting. If the stinger is still present in the skin, it must be carefully removed as pressing or squeezing it can cause more venom to get injected into the skin. The area of the bite must be cleaned properly. You can also wash the area with a solution of baking soda and water. If you are experiencing itching, a solution of salt and water may be applied to the area. Applying an ice pack or any other cold compress will help to relieve the swelling. Witch hazel is very effective in reducing itching and inflammation caused by insect bites. You can also apply vinegar or lemon juice to the bite. Application of aloe vera gel helps to soothe the area and alleviates itching and swelling.
