 [ Symptoms ] what are the long term effects of being stung by killer bees  i was attacked by a swarm of killer bees in central america in 1999 i did not suffer from allergysinus problems until then now i have allergy and sinus issues several times a year could there be a connection or any other long term effects it was severe enough for me to be hospitalized [ Disease ] i do not think that your attack by killer bees triggered your allergy and sinus problems a long term effect of a bee attack for me would be death assuming i did not have my epi pen handy but unless the bees resulted in permanent neurological damage    something that you would have experienced soon after the attack    then i do not feel there would be any long term effects other than killer bee phobia
