Wasp and Bee stings

Patient: Hi there,A couple of years ago I was stung by a wasp or bee. Sevaeral hours later I had severe abdominal pain and was taken to hospital where I had my appendics removed. Although they discovered they were actually fine but I had swollen lymph nodes. I didnt at the time think but having researched it, I am starting to suspect it may have been a reaction to the sting. What are the chances of another reaction to a sting as I have a wasps nest in my garden. I dont fancy having any more organs removed lol. Thanks
