Hello. I have a question in regards to an xray Iihad a few days ago. The rradiologist said he was really backed up and would give my pcp the resultsIin 5-7 business days.

so I had an xray of my back; cervical, thoracic and lumbar. The tech said he kept having to do them because he thought the films were not correct.
I saw a few that had 3 (thumb size) white spots by my spine. What can this possibly be???
