My nephew owns several pharmacies.  He thinks it is ringworm.  No bite in the middle.

Appears to be 2 punctures on the right edge of the red ring.

Might be ringworm, a fungus infection.

Is it feeling mushy inside the ring when you work a finger over it while outside the ring is firmer ?

Wash hand well afterwards in case it is ringworm.

Ringworm?

There is always the expertise of a health professional who has experience with tropical ailments.

My spider bite resulted in significant  swelling of my hand and itchiness.

That's what i said, looks the same as ring worm when dogs have it....

100% sure it's ringworm some people are more sensitive for example my sister came to Thailand and within 4 days she had it all over her hand from touching a puppy on the street. I've always had some form of fungus on my hands but it's not noticeable because I was a teacher in the UK soon as I put on the antifungal ointment you can start seeing patches of your skin peeling off on your fingers and hands. It's starts off extremely itchy. By the cream that I posted earlier and keep loads of it in your house and use it in your on your hands and in your crotch

Ringworm is unlikely to appear so suddenly, in one location only, immediately after a bite.

7 days later and almost gone. Thanks for everyone's advice, first time I've had a bite like this and was a bit scary.

I had similar to that a few years ago. I had trapped one of those red millipedes under my arm while I slept.

Only thing I know about this is that Thai doctors will know what it is. I don't understand why the OP is posting about it instead of at the hospital. It's not like they cost a lot in LOS.

Too lazy to go out!

Unhelpful post removed.

 

Definitely not a centipede of the scolopendra family because not only is the fangs going in quite painful, but the venom results in excruciating pain that lasts for hours. There's no way you would've slept through that. 

Tick bites can leave you with Lyme disease, but  the ring can take many days to form. The ring is a rash, treated with antibiotics if caught quick. I had it while living in Germany. The doc caught it in time as I didn't wait more than one day after the rash appeared. If it appeared overnight, it is not a tick bite. If a centipede, you would  be in severe pain. My best it is a spider bite. 

You were all right, and I was wrong.

It kept coming back and was ringworm.

 

Five months later ..........

20 days on broad spectrum antifungal pills, no alcohol or weed. Seems to be going ..... Finally!

 

Ooh .... that's a nasty looking bite.  I never bothered about spiders in Thailand as I didn't think the common ones in the house were a serious threat.  Even those big scary looking Huntsmen are supposed to be harmless to us.
