What is the 'stone like' stuff found embedded in my skin/just under the skin?

I got these dark spots like three times already this past six years. Everytime I saw those spots, I knew that there were a stone like structure, may be 1 mm diameter in size, that can be squeezed out from the skin. I got one from the back of my upper arm, one at the back and now one on my side. I keep the one I found six years ago in a tissue paper and I kept them and it does not decompose. I just can't stop thinking of what it might be, and how it can be found just under my skin/embedded slightly deeper under my skin.

Anyway, it's possible that it's dirt, oil, ingrown hair.


Or calcium deposits.





Go to the dermatologist. Or doctor.
