Hello and thank you for your query
The type of lesion that you have described is that of a white head.
It occurs due to obstruction of sweat glands by dirt and exfoliated dead cells.
White heads and ache may be due to some kind of hormonal
You can wait for them to resolve.
However, if they get worse or do not resolve then you can consult a dermatologist
i hope you are satisfied with the answer.
