Cat Scan

tomorrow I am going to receive my very first Cat Scan. I have been suffering from non stop head aches for the last 2 weeks. Sometimes very mild but other times very brutal. The doctor has called in many prescriptions for me to help but none have completely taken the head ache away. So I called on Monday to see what I should do. The nurse talked to my OB and told me she was going to get me a CT Scan as soon as possible. She called me later to tell me when it was and to tell me if my eye site starts to get funny, get really dizzy, or I black out to go to the emergency or the labor and delivery room asap. She said it was very serious. Which freaked me out. All along I thought it was just a head ache. It could be something else. I do get very strong head aches a lot. So I'm a little scared about tomorrow and about the cost. Its not cheep to get a Cat Scan.
