Any ideas what this could be? Doctor is sending me for tests under microscope etc but have the worst health anxiety. It is a small pin prick sized bump that I can pinch and move around, hasn’t grown in a month since I noticed it. Clearly got white something there as well. I squeezed it once and silly string type puss came out and it went red around it but other than that nothing. It came up around time of my last period hence why I thought it was a spot but doesn’t seem to be going away.
