Noticed them when I woke up their all over my body.. I’m pretty sure I got them at night but they itch severely and they kind of look like they are getting bigger. I notice them mostly on my upper back and up arms their every were and they look red now. I’m not sure if their bed bugs (god forbid) or what. anyone have any ideas? I have a very new mattress I checked every where but didn’t see anything

This is a photo of my chest as you can see they are red and inflamed
