The first few days after the sting are the worst. It can be a few hours before you will notice a lot of swelling, and it can take up to a week before you feel and look back to normal. After the swelling goes down, it is likely that you will have bruising that takes a few days to go away. Even if you were only stung near one eye, you may have swelling and bruising across the bridge of your nose into your other eye. Overall, it can take up to 7 or 8 days for a full recovery.
