To speak to the doctor about a wasp sting or is this normal?

[Hopeandeggs]

We were away from home last week and I got stung for the first time. Within minutes it went from a tiny raised 1cm circle to a huge raised section of my arm. I had the obvious pain and itchyness and discolouration.
I've also had pins and needles, headache and nausea. The swelling took a few days to go down. It's still itchy now.

Is this normal for a sting or do I need to be careful and mention it to the doctor?

I had a nasty insect bite and went to the pharmacist who took one look and told me I needed an urgent gp appointment for antibiotics. So go to the pharmacist and if you need to see a gp they will know.
