When Insect Bites Cause Swelling?

When an insect bites, it releases saliva that can cause the skin around the bite to become red, swollen and itchy. The venom from a sting often also causes a swollen, itchy, red mark (a weal) to form on the skin. This can be painful, but it's harmless in most cases.

What insect bites that cause swelling?

Tick bite. Bites can cause pain or swelling at the bite area. They may also lead to a rash, burning sensation, blisters, or difficulty breathing. The tick often remains attached to the skin for a long time.

What to do for an insect bite that swells?

Use a cloth dampened with cold water or filled with ice. This helps reduce pain and swelling. If the injury is on an arm or leg, elevate it. Apply 0.5 or 1 percent hydrocortisone cream, calamine lotion or a baking soda paste to the bite or sting several times daily until your symptoms go away.
