I went into the beekeeping business, 1000 hives, after college, so much for my education! I've probably been stung well over 10,000 times, you get used to it to the point that a mosquito bite is much worse. Bee stings have been proven to prevent arthritis. The stinger on a honey bee detaches along with the poison sac which keeps on pulsating, pumping in the venom. The mistake people make is to pinch the stinger to remove it, squeezing in all the venom from the poison sac. To prevent this it's best to scrape the stinger off to remove it. The method I've found is best to keep the swelling down in sensitive people is to apply mud to the sting right away and let it dry, drawing out the venom. There is also a product called Sting-Eze that does much the same thing, but mud is easier to come by. If you are stung close to a hive move away slowly without flapping your arms to avoid multiple stings. When a bee stings you it emits a scent (pheromone) that sends the bees into defense mode, the faster you move the better the target you make. It's best to stand still till the bees mellow out.
