Acne or Cyst??

Emily

This has been on my chest right below my collarbone for a month now. The only reason I didn’t have it checked out sooner was because I assumed it was from sweating more since it’s summer and I do get acne monthly. Then the redness went away and again I thought it was just pimples but it hasn’t cleared up anymore and it hurts. Nothing comes out when I pop it. They also itch. Does anyone have any ideas??? Hopefully I can get an appt with the dermatologist tomorrow.
