The gauge of the needle, what the needle is being used for (IV, tattoo, blood draw, injection, etc.) all have an impact on the sensation experienced when a needle penetrates the skin. With injections in particular, the solution's thickness will definitely contribute to it. The thicker the solution, the more painful.
It feels like a sharp pinch, and sometimes you feel the needle sinking in, then it's just like stinging really bad, and you don't feel relief when the needle's out.
to point the right direction ***correction by cw - the needle always points north.
In my experience, it's much less uncomofortable than a fingerstick. There's a tiny prick as the needle enters the skin, but no continued pain with the needle in place.
In my experience, I can't feel it with my fingers and definitely don't feel it in my day to day life.
