Small Bump On Upper Arm With Small Grey Dot, White Pus Came On Squeezing. What Is It?
I have a small bump on my upper arm with a small dark grey/black dot. I thought it was a blackhead . And squeezed it and white pus came out. The more I squeezed the darker it got till it was black. The pus is a weird consistency.like stringy and almost cottony if that makes sense. And I don t know if I should go to a doctor. Please help.

Hi,
This could be a sebaceous cyst. The contents that come out when it is squeezed are often whitish and creamy in consistency. There is a risk that it becomes infected if you squeeze it. In which case it would become painful and red and I would advise a visit to your doctor. If it does not become infected then you need not do anything but I would advise you do not squeeze it anymore.
