What are these on my legs!?

[morbidd]

Excuse my thigh, but could anyone tell me what these bites are caused by?

They are like raised bumps and colourless. Also a little itchy and have just appeared .

Thanks

Look like hives, got any antihistamines or hydrocortisone cream?

Thank you for the response. They have a little red dot in the middle of them so I was worried they might be flea bites, however research suggests a mosquito or gnat as they are too big for flea.

I'd say heat bumps, and it's just the pore / hair folicle you can see

Most of them have already disappeared which seems odd!
