I'm sorry about your headaches. You should be able to request a copy of your CT Scan from the location you had it done. It is every patient's right to have copies of their tests. Normally, they will give you a printed report, that gives you information on everything relating to the CT Scan.
I would definitely try to get in with another Doctor (Neurologist), so you can find real solutions to your headaches. You deserve answers.
You're in my thoughts.
