Bee sting allergy

I have a 14 year old daughter that was stung by a bee on Tuesday afternoon of this week, while out of town at a summer camp. This is probably her third or fourth sting overall.  It seems like each sting has caused a reaction that has been a little worse than the previous reaction. She has had no swelling or itching on or near her mouth or throat, and she has had no signs of respiratory distress/breathing difficulties. Can bee stings cause reactions that are of a progressive nature? I am concerned about the possibility of some of the more serious reactions developing over time. This latest sting is definitely worse than the one before; I thought the one before this one was bad!! She has MAJOR swelling; the swelling is at the site, but it is also well beyond the site. The other compaints were intense itching, pain, and "stretchy skin"(her words) The medic at camp was concerned about cellultis, and also that her symtoms (symptoms) were increasing, instead of decreasing.  She was taken to the ER very early this morning to get checked out. She is going to be fine. They treated her with antibiotics, and several other medications. Does anyone out there have any answers or experiences with this type of allergy? Thanks.

Hi,
A bee's stinger works like an automatic pump -- the longer it stays in, the more venom it releases -- so get it out as quickly as you can. Look for a little black dot in the center of the bite, and scrape it off with a fingernail or pull it out with your fingers. Try not to squeeze the stinger, though, because that could release more venom. Once you've removed the stinger, wash the sting area with soap and water. Then apply an ice pack for 15 minutes or so to minimize swelling and relieve pain. Give your child acetaminophen immediately to relieve pain and burning and children's Benadryl to reduce swelling.
The familiar symptoms of bee and wasp stings include pain, redness, swelling, and itchiness in the area of the sting. Multiple stings can have much more severe consequences, such as anaphylaxis, a life-threatening allergic reaction that occurs in hypersensitive persons.
