• You think you need to be seen
• Sting looks infected (red streaking from the sting area, yellow drainage) (Note: skin infection doesn't start until at least 24-48 hours after the sting. Any redness in the first 24 hours is due to venom.)
• Swelling is huge (e.g., larger than 6 inches; entire hand is swollen)
