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.

If you want a lerger gauge for whatever you are doing. I DO NOT recommend using an injection needle for the sole fact that it will cause MORE pain and bleeding, as well as potentially destroy a nerve or vein depending on what you are piercing and the size of the injection needle.HELLO!Piercing needle?PIERCING needle.Assuming you are piercing,and not injecting,NO!What kind of person asks that?PIERCING NEEDLE.That answers your question.
