Photo taken on day 5. Day 1 looked like a mosquito bite, though only the slightest itch. Red dots appeared on day 3, grew on days 4 and 5. Actual color is more like wine.

 

looks to me like a spider bite .

Sure it was a bite? I get reactions like that to certain allergic vegetation when I cut weeds around the garden and hedges, although 3 days is rather long. 

It's not a bite. I get these all the time after doing yard/garden work. Neosporin or other anti-bacterial will make them go away in a couple days.

the look and spread makes it appear to be an allergic reaction... as others say above.

Could be a centipede bite .Had similar then did some serious surface spraying dead centipedes every where .! The Thai will know ?

Why don't (didn't) you go see a doctor?

 

Looks like my arms after I scratch them, which usually happens while sleeping.  0.1% Betamethasone (corticosteroid) cream or 0.1% Betamethasone with 2% Fusidic acid (antibiotic) helps prevent more scratching, at least in my case.

It certainly looks like an allergic reaction to something. Some pesticides will do that too. It certainly is NOT a centipede sting as you would not be on here asking the question, you would be in agony! Try anti histermene .

A change of Meds can do that.Had just the same Its allergic as some have said

A nonsensical post has been removed.

 

I agree this is probably not a bite but some type of contact dermatitis. I don't know to what but I've had it too after being outdoors.

 

Steroid cream may help.

Removed a troll post.

Use simple baking soda  make solusion in water and use a cloth to put around bitten /irretated area works better than all the creams in the world 

this is mostley from garden plants  i use it after cutting.

Quadriderm / Buy Original!  Lasts long. Small amount massaged in every few hours, or even better a bit extra and cover with a good bandaid and gone over night. Excellent for all kinds of small wounds, bites, rashes etc. etc. MS>

Bed bug bites?

yes bed bug bites then get like that after you scratch them unconsciously

Could be a rash caused by the Rove beetle. The blood of this beetle is very venomous. These are small sleek beetles that can crawl on you while you are sleeping and by lying on them or squashing them uncounsiously you can come in contact with that venom and get very bad skin rashes. See link here

I see some of these beetles from time to time in our house and kill them immediately. Best to squash them with a tissue paper and wash the hands after that.

 

They look a bit like a sleek earwig. But I think this one can also fly, so watch out for them.

 

Check your bed and sitting furniture, sofas and cushions for them.

 

Good luck

Did you apply anything to the 'original ' mosquito bite?

Many liberally apply Tiger Balm type creams, which may relieve the itch but causes allergic reaction in some.

Could be dermatitis, starts with small pimple then spreads under the skin. A good cream with ant-histamine and cortisone would probably do the job. 

 

Thanks for the responses. Seems none of them fit. It's 2 days later. The only change is the color is fading.

 

> allergic reaction, contact dermatitis

Those are surface reactions. The red areas have the same skin feel as the surroundings. The red is under the skin.

 

> spider bite

The ones I've had and photos I've seen are all round with an obviously more damaged center spot around the bite.

 

> bed bugs

They start out red and itchy. Mine started looking like a mosquito bite, i.e., skin colored.

 

Itching is a symptom of all of the above. Mine has the slightest itch on day 1, none since.

 

> scratch myself
I do that. Always the same spot on my thumb. Looks like a shaved off a micro layer of skin. Never looked like a mosquito bite.

If I'd asked if I should see a doctor, would you have asked if I knew what it was?

When I walk 18 holes of golf in hot weather I suffer from Golfers Vasculitis. Usually disappears after 2-3 days.

not rove beetle. they give far more long lasting grief than the picture. his bedbug bite will be gone without trace in a couple of days rove beetle leave infection that lasts for weeks and subsequent mark that last for years

If its the same centipede that bit / stung me then he would probably have felt the burning pain almost instantly.

There are no signs of insect contact marks, i.e. bite marks or as with centipedes the damaged skin around the contact point.

Red "under the skin" is perfectly compatible with contact dermatitis. There are different types of contact derrmatitis, nto all are of the eczemous type. The picture you posted looks exactly like purpuric contact dermatitis.

 

The redness you see is actually due to bleeding into/under the skin. The toxins in some plants will do this.

Bingo! That's a 100% fit with my symptoms. Had no idea contact dermatitis could be expressed under skin surface. Thanks.
