Something stung me in my bum! (TW: pic included sorry)

[Sushiandunagi]

So I’ve been bitten or stung in my bum!! Two days ago - completely unprovoked. I couldn’t find or see little bugger that did it whilst I was minding my own business.
it hurt like hell, now it’s all red and swollen. I literally look like a baboon! Problem is, I’m taking antihistamines and it’s not getting better. Can someone comfort me please? Is it a wasp sting? Has someone’s had any similar? Obviously not worth GP’s time… but it huuuurts!! one pic - how it started and another one - how it’s going.

Dd had been stung 3 times in 2 days by wasps. They looked similar to this

Ouch :-( Which way round should the pic be? Is it getting bigger or smaller?

Have you tried hydrocortisone cream? Any steroid cream would do if you have any in
Otherwise an antihistamine cream.
I have heard that the older antihistamines like Piriton (chlorphenamine) are more effective on skin than the newer non-drowsy ones. May be worth a try

First thing, I would take an antihistamine & some Ibuprofen & then get an appointment at the doctors, either telephone or online & send copies of the photos you have posted.

Looks like a horse fly bite

@liveforsummer thanks for letting me know - I think it may have been a wasp but I wasn’t sure.
@SaltyCrisps it’s getting bigger 😰
@QueenOfHiraeth ooh, good idea! I’ll try that thank you 🙏
@Nat6999 i was planning on avoiding getting my GP involved because I really think doctors have more important things than looking at my baboon bum. If anything fails - I might try it though.
@TerrifiedandWorried it did sting a lot!

I thought Horse Fly bite too :-( I agree with others. Get along to your GP to have it looked at x

Horse fly, little bastards. I had a bite on my arse too, it got infected so be careful of that.

I was going to say horse fly bite as well. I got bitten on my arm a few years back and it looked like that and it was so painful! Much sympathy to you. Perhaps you could show a pharmacist and see why they think?

While you wait for an appointment, Tiger Balm is actually more soothing and effective than antihistamine cream. Take the antihistamine tablets but apply tiger balm topically. I have had some really evil bites in Asia and this has worked for me.

Thanks everyone for your replies and thanks to those who advised to go see a doctor - after much deliberation i did it and got prescribed antibiotics. Apparently it was a horse fly and indeed it is infected. Trust my luck!

Glad to hear you got an appointment and they're sorting it out, OP
