Moon, try taking a half dose of benedryl. It might be just enough to take the worst of the sting effects away without making you feel weird. The goal is just to take the edge off and keep swelling manageable. Apply hydrocortizone cream to the sting often.
Though a few people get worse reactions to stings with each successive sting, actually most people get less of a sting reaction if they get stung a couple times a year.

Honeybees usually just want to be left in peace, they don't typically come after you. A wasp can sting many times, and is always more aggressive.
All bets are off if a bee or wasp gets stuck in your clothes.

A honeybee can only sting once, her stinger with its minute venom sac gets stuck in your skin, and then she dies.
If stung by a honeybee, scrape the tiny stinger out of your skin as quickly as possible. Don't grasp it and pull, but rather scrape it off. That's because the tiny venom sac on the stinger is still pumping venom into your skin, and grasping/pinching it will squeeze more venom in. Scraping pulls it out without pushing more venom into the wound.
If stung by a wasp there will be no stinger embedded in your skin. That's why a wasp can sting over and over.
