Is it eczema?

I'm not sure what it is and I need help figuring it out.  On both upper arms I have tiny little red spots that itch.  It looks kind of like eczema but Idk.  Their so extremely tiny, I have had this as long as I can remember, it itches ALMOST all the time.  It's irritating.  My 10 month old son has eczema.   So, maybe I have it too?  Uhm, I have looked at pics of eczema on google images and none look like mine...so that's mostly what makes me so unsure about it. I think it might be a very slight amount of eczema and I have some cortisone cream but I'm afraid to use it because if it's not eczema it might not be a good idea to use it...:(  So, any ideas?! What the heck is on my arms?! O_O  and a few of these teeny tiny spots are red with a little speck of white and the others are simply red.  Hope someone can help ASAP!!!!

Hello,
It can be due to keratosis pilaris. Treatment includes tretinoin or Triamcinolone cream or Adapalene, a retinoid medication. Exfoliation, intensive moisturizing creams, creams and lotions containing alpha hydroxy acids and urea may be used to temporarily improve the appearance and texture of affected skin.

Please take a second opinion from a dermatologist if the symptoms persist. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
