Hi Angy,
Sorry to hear that you encountered such an ill-mannered wasp. Unless the wasps in Scotland are more potent than they are in this country, that was an unusually severe reaction. It's not unusual for the area around the sting to swell, and throb, and get numb, but it
is unusual to feel nauseated, dizzy, and light-headed. Of course, being stung multiple times can cause those symptoms, especially in sensitive individuals. As long as you didn't experience any serious difficulty breathing, or notice a tightness in your throat, or a rash on your face and/or chest, then you probably didn't have any anaphylactic effects, and you don't need to take any special precautions in the future, unless your symptoms get worse, the next time it happens.
I'm amazed that you were never stung before. When I was a kid, I was always poking around in the wrong places, (or throwing rocks at wasp nests), and I got stung pretty often. After I grew up, (and stopped chunking rocks at wasp nests), I didn't get stung anywhere near as often.
I agree with your husband - whenever I got stung, I always tried to get revenge. LOL.
