Do i have a bee sting infection? been 3 days and still itches a lot. is turning purple and sting site is whiteish and slightly raised. also warmer.

Bell venom allergy: It's much more likely that you're allergic to the venom the bee injected into you. Itching is a hallmark of allergy - and if the area is inflamed like that, it's probably all allergy. I would try putting some ice on it (10 min on, 10 min off), take some benadryl or other antihistamine every 6 to 8 hours and see what happens. If you develop a fever, or the rash area extends, you need to show a doc.
