What are the symptomsof an insect bite or sting?

Pain, redness. An infected insect bite will get more painful and redder as time passes. The area involved will also increase, and it may swell and start to drain. Warm compresses can help you clear the area over time; most minor skin infections don't need oral antibiotics, but if it's not improving with home care you might, so see your dr if it doesn't clear on it's own.
