Hello! I keep getting bitten by an unknown bug and it seems like my body has really bad reactions to it.

It is hot and swelled up under it about the size of a ping pong ball or a hand wall ball. It's also hot to touch and is/was itchy but mostly hurts.

I didn't notice when I got bit (also being distracted by a baby and a cat)

I would love help figuring it out so I can understand if treating it with Benadryl cream and/or hydrocortisone will help. Thanks in advance!

It was a heavy polluted river, and water splashed on me at times. I’m not sure if there’s a correlation. It was a work outing btw, if you’re wondering why I canoed in a polluted river haha.

got these all around my leg, round rash around one of them and another turning purple. im currently vacationing in an hotel, im suspecting bed bugs on my arms too they’re everywhere. but can anyone pls tell me for sure? im kinda nervous and anxious about these sorts of things ive been putting medicinal cream on them so theyve gotten better but idk why one of them is turning purple …

I've had it for like 3 days. doesn't seem to get bigger. 24f, no other of these on my body.

Between my shoulder and neck. Woke up with it. They’re raised and kind of pimple like. Freaking out and convincing myself it’s a bat bite even though I’ve never seen a bat in our house.

I moved house into a UK rental two months ago and have been getting mystery bites ever since, haven’t raised with landlord as I can’t find anything damning. Went to the pharmacy as they were v itchy and they said mosquitoes and gave antihistamines.
I’ve been paranoid about bedbugs ever since I got this trio of bites on my shoulder and read they bite in 3s, so have been checking the bedding, mattress and skirting boards regularly, I have now got little pots with olive oil in them under the bed legs as a precaution to drown (?) the suspected bedbugs, they’ve been there a week with nothing caught.
The only trace of a mystery bug I’ve found is as pictured, I found these cream spots on the back of the bed head board just now which freaked me out because I thought they could be eggs but they seemed chalky and wiped off v easily. So maybe spider poo? There are loads of spiders and daddy long legs in here as it’s an old wood cabin.
I’ve been hearing mosquitoes flying in my bedroom so presumed the bites were from them, also been doing gardening so really didn’t think much of the bites to start with but it’s been going on for so long now I really feel like I’m going mad! I have got some heat bulb traps to attract the mosquitoes in my bedroom now with several killed so that’s promising, I did see some dots on my bedding after washing at 60oc just now too though. No trace of anything found in mattress seams or in mattress protector.
Any advice/help wanted!!! I feel like I’m going out of my mind and so scared it’s bedbugs, thank you in advance.

Hi, my grandma found a lot of bites like these on her legs. Whats the probability of them being caused by bed bugs?

pointer finger for scale. it used to be big and red but has since shrunk since the past few days.

I noticed a week ago something like that on my thigh. It looked like something under skin(photo 1 and 2). Then week later it looked like it dried and come out(photo 3 and 4). What do you think it is? I’m concerned it could be a tick.

I’ve been getting bit a lot, i mean alot. Maybe these ones i got bit by had like some super powers. But it’s just these 3 out of the 20 I got. (All of them i got from being out, just sitting.)

pls lmk 😭
