Most insect bites are minor annoyances and can be easily managed at home.
The following situations, however, call for medical attention. You have redness or streaking around the bite, yellowish pus and fever. These are signs of infection. You suddenly have trouble breathing, develop body-wide hives or feel faint after being bitten. You may be having a body-wide allergic reaction to a bite, which causes your airways to swell shut.
