Hello. I noticed this thing. On my back I have dozen of little red spots (it s not a rash, no bumps, just skin colored differently) and they shape up a little square. I am thinking maybe it is because of bed because it has back, and I put my back to it when I m sitting, and it has this pattern with holes, so I was thinking that could of happen because I was resting on it a lot for last few days. I m scared a little bit. (sorry, english is not my mother tongue).
