Bee stings aren't very bad. They feel like someone pinching you. Yellowjackets and Red Wasps are a different storry though. They feel like someone shot you with a high powered pellet gun, and then the sweeling, and throbbing begin and begins to feel like somone is holding a lit match right on your skin.
I got stung by what turned out to be a paper wasp the other day. It didn't hurt to bad, just felt like a quick prick with a needle, and didn't linger very long. It was just slightly irritated and itched a little afterwards, but it left a nasty welp. it was dark red in the center, then pink for about the size of a nickle and then a swollen puffy ring around that the size of a quarter.
