When I get stung by a bee first thing I want is to pull the stinger out, and if the smoker is lit puff a good blast of smoke on it to disguise the alarm pheromone (banana smell).
Stings do not bother me like they use to and I find the more excited I get the worse it seems to swell up.
Benadryl works pretty good on controlling the itch and swelling, I rub some of the gel on if it gets too itchy.
If you are allergic you will have breathing problems from your throat swelling, an epi pen would be real handy at that point in time, could save your life.
Other remedies could be just about anything from tobacco, a cut potato, cold pack, any number of over the counter sting meds, some different plants, etc.
