Insect bites?

[Chimichangaz]

I was gardening last night, putting some bark in my borders wearing shorts and top and I felt a sharp sting on my inner thigh. I looked and there was a small red mark like a blood blister, quite itchy. There's one on my shin too. I've had a shower tonight and am shocked at how red and infected it seems (the one on my thigh) - there's a red centre and then more redness spreading out and it seems a bit swollen. Wondering if it's an insect bite or maybe a wasp sting and what I can do to treat it. It's quite itchy. Any advice? TIA.

Have you taken an antihistamine? If not, do so and regularly according to the packet instructions.

I was taught that insect bites are actually rarely infected but some of the reactions are very dramatic and it ends up being hard to tell the difference between what is a very impressive wheal and flare reaction to an insect bite and one that is actually infected - so you end up giving out antibiotics to be on the safe side.

The redness goes down, as it would have naturally anyway and the patient is convinced the antibiotics 'worked' - and nobody knows if there was an infection or not.

Anyways - take an antihistamine now. It's what they are for.

Thank you @AnnaMagnani
I'm going to nip to the supermarket now.
