What are these little red itchy bumps on my arm?

Itchy red bumps with white centers on arm?

• i have no idea what this is i dont go out of my home much so i dont know where i could have got this from the only place i can think of that i went to was my 2 month old sons doctors appt to get his shots a few days later i had one little bump on my arm that was itchy and looked like a pimple but i just thought it was a bug bite and ignored it but i started scratching it and i popped the white part now i see more popping up on my arm its starting to spread up my arm and i dont know what to do because i dont want to give it to my son. i also still haven't had my postpartum appt yet could this be related some how?

• Answer:

  I think you need to check for spiders. I have a 2 month old as well, and this doesn't seem like anything I went through at all. Nor does it really sounds like anything you'd have postpartum, but I've been wrong before. I encourage you to just check around for spiders in your household! congratulations on your baby!
