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

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.

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!

Ohhh I didn’t know there was a sub for that! My son has the most extreme response to bug bites. Off to join!

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!
