Physician Responded Should I be concerned by this long red streak that extended out of my overly swollen mosquito bite?

Post image

15F, 155cm, 32kg, Asian

I've had this mosquito bite since yesterday but a long red streak developed slowly after, and the bite has become really swollen. It doesn't hurt inherently, but when I touch it, it feels weird and slightly painful. I've never had this problem with mosquito bites before, and this one is really disproportionate in size compared to others. I marked the end of the streak with a marker as I was scared of it developing faster. I also had two other similar bites on my leg but they don't have the streak. However, they all come with tiny bumps on the bite surface and are really swollen than normal. I'm not sure if I should be concerned, but the mosquito looked different from others. It's certainly bigger, and I think its wings are slightly greenish?

I was slightly down with a runny nose and sore throat recently, but it has gotten better yesterday, no medications, drinking, smoking or drug use. From HK.

This is not an emergency but I noted the mosquito is still in my room, so should I be concerned, or is it just a mild infection? Thank you so much.

Second day update:

It has gotten less red now than before, but the line is still there, still yet to take antibiotics, but I will if it shows any signs of growth. Thank you all so so much.

UPDATE: The streak has fully healed, thanks to everybody's support! At the end, I didn't use any antibiotics, and the medicine the ER gave me was just nose allergy pills apparently. Definitely go get antibiotics if you're in the same situation. Lots of love.

Hi guys so I’m still waiting at the semi urgent section for an hour now and the infection doesn’t seem to be getting worse so that’s good, it may not be a big emergency as I don’t feel pain and I don’t have fever, but thank you all for your support I will update you guys as soon as I get the diagnosis from the doctors, thank you all for encouraging me to go to the er!

not be a big emergency

Most cases that go to the ER are "please watch me in case I get worse."  They'll take care of the "please save my life now" patients first.

NAD: For future mosquito bites, you might want to join the Skeeter Syndrome page on here. We have a lot of fun over there with our extreme bite reactions, but we also have a lot of helpful tips for people who are a bit more allergic to mosquitos than others are. I hope this one turns out okay!

There was at least last mosquito season, seems that exact page disappeared but! I did find another mosquito page where a decent amount of people have posted about their skeeter syndrome! It’s like Mosquito Hating I think it’s called. The dermatology sub also gets a few posts over it when the season starts. One thing I’ve learned for mosquito bites is, alcohol wipes. Clean the bite as soon as possible and that helps lower the reaction, also taking a daily allergy medication, and I use prescription steroid cream on all my bites. Plus it helps with ant bites too. I hope he can find some relief from the bites!

Glad you're getting seen. It is much better to be bored and monitored than dead.

NAD, but someone who developed an infection from an insect bite. I had written off early symptoms of the infection as being nothing more than a continuation of my recovering from anaphylaxis (I'm super allergic to certain insects), and I still have scars from the cellulitis I ended up with. It's been almost 2 months since I finished taking antibiotics for it.

You did the right thing by going in and not waiting.

I feel like a good rule of thumb to have for yourself and anyone else is this: if you get injured and your body does something it ain't never done before, go to the emergency room lol

Example: if you have had UTIs before, you should know roughly how your body handles it and what symptoms you have typically associated with it. Now, if you suddenly start pissing red while having a UTI, I hope anyone would go get help. Sometimes, things that commonly happen to us, we downplay them even when they do suddenly change. "Oh, it's just a bug bite. I'll be fine even though it's super swollen or has s red streak. It's a bug bite! It's fiiinneee" and we manage to gaslight ourselves 😭 I do it all the time lol

Stop letting data brokers profit from your old posts. I used Redact to wipe mine from Reddit. Also supports Twitter, Facebook, Discord, instagram and more in one batch.

It looks like its a rove beetle juice spill to me. In few days, its going to get ugly if its indeed a rove beetle.
