Part of my arm has a skin patch that feels like goose bumps?

I already know what Keratosis Pilaris is, I have it on my upper arms.





On my arm there is a patch of skin a bit bigger than a half dollar coin.





The skin isn't really that bumpy, but it looks like goose bumps. What is it and how can I get rid of it? It has been there for around 3 years.

My son had that on his chest for years. We could never figure out what it was. I suspect it was eczema. We tried all kinds of creams and ointments. It eventually went away on its own. If it is really bothering you, you might want to see a dermatologist.
Reply:I have that too! But i have NO CLUE what it is.
