Insect bites and stings, especially from bees, are very common for people of all ages. In most cases they are usually harmless, however, some people can experience an allergic reaction that can be mild to severe. When the insect stings you, it will inject its venom into your system, which can trigger an allergic reaction, causing swelling and redness to appear in the bite area. Bites from insects like wasps, hornets, horseflies, and fire ants can be painful. The affected area usually turns red and inflamed following the bite. On the other hand, mosquito, flea, or mite stings cause mild irritation and small bumps at the site of the bite or sting. In rare instances, an insect bite may be responsible for transmitting diseases to a human such as Lyme disease or West Nile Virus. Sometimes, mosquito bites can cause malaria, dengue, or other viral diseases that may not show symptoms in the form of a skin rash but can present a fever and other symptoms. For an insect bite that leaves a visible mark on the skin, any general physician will be able to identify it as a bug bite. In severe cases, you may need to check with a dermatologist.
