Question) I am worried because I have red spots on my skin.

I don't know when it started... but tiny red spots began to appear on my arm.

I don't have any symptoms like pain or itching, so I'm wondering why these spots are appearing...

At first, I thought I had been bitten by a mosquito, but it hasn't gone away since it appeared. There aren't even any mosquitoes in this weather lately, so I don't know why these spots are forming... If you look closely, it even looks like pooled blood.

It doesn't hurt, so I feel like I can just leave it alone... What should I do...?
