Thanks for your question.
It is difficult for me to understand what you mean when you have given a description like this, which is not exact enough to be certain about. However, for your information it is a very common area to have them and should not be embarrassed. These white dots can vary in size from a tiny size to a size as large as a pea, or even bigger. Also stop thinking that the doctor will find this unusual.
The only satisfactory solution for these white dots is to get rid of them, especially to have the larger ones removed.
It is a very simple process which can be performed under local anesthesia and many doctors can do this in their own minor surgery clinic, so you do not need to go to hospital.
So please stop worrying and think about consulting your doctor for this problem. You can do this just to confirm what I have told you.
