What are raised bumps on a child that have a whitehead on top and hard on bottom?

My aestician told me that the white spot on the tip of my nose is an impacted whitehead and should be removed by a doxtor. What needs to be done and who do I go to ?

My four year old son has little white hard bumps appearing on his forhead and neck, what coul they be?

We saw a boat on top and a car on bottom, being towed behind rv. it had crank handles to remove car and then lower boat into water

These bumps were going away, but now I have had them for a while, they don't really look like pimples, they are small and white and red around them. If I just scratch them with my finger nail the bump bust...

I get hard bumps on my face, most of the time nothing comes out when squeezed.
