Neck and Right arm

I been getting these cluster of small bumps on my arm for some years now. They don't itch there not red, they math my skin color (African American)

A few weeks ago I noticed small dark cluster on my neck now the only thing new i been using was a bath glove and I been scrubbing my neck alot and hard since the end of dece and it appear sometime after that.  I use dove for soap and coca butter for lotion. It does itch or anything.
What could it be

Hello,
Without examination, confirmation of a diagnosis is tough, but it sounds like keratosis pilaris. It is a common genetic follicular condition that is manifested by the appearance of rough bumps on the skin like goose bumps and hence colloquially referred to as "chicken skin".
Keratosis pilaris occurs when the human body produces excess keratin, a natural protein in the skin. There is currently no known cure for keratosis pilaris, however, there are effective treatments available which make its symptoms less apparent. 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.

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.
