"Told I was wrong about my symptoms"

I came in with a painful bump on the back of my head, the doctor tried to tell me it was just part of my skull, but it wasn’t as it was asymmetrical to the other side, causing me pain and headaches. Only once I repeated the symptoms did they did say it was swollen compared to the other side. Then said vaguely it could be this, could be that and gave me antibiotics. The doctor was 4 minutes behind schedule which i was okay with but the whole appointment felt very rushed and like I didn’t receive good quality care. Doctor even asked if i was pregnant as I walked out the door. So unprofessional and now I have to seek a second opinion because more painful bumps have surfaced, and the doctor didn’t explain to me that this might happen, just tried to tell me I was wrong about the symptoms i was experiencing. Disappointed in this service
