CT Scan

So they called me yesterday and scheduled me for a CT Scan for my eyes right away. I went this afternoon.. it was painless. I just had to lie down on a machine that looks similar to an MRI machine, but not as big or enclosed. They did a scan of my eyes. The tech said that the main difference is that CT Scan uses radiation to take the pictures and the MRI uses magnets. The whole thing took like 10 minutes, including setting me up. The wait was more than 3 times as long. They said the doctors should have the results in 48 hours. I kinda wonder what my doctors are writing to each other on my records. I got a call from the PCP nurse reminding me that I needed to get a follow-up blood work to check my thyroid levels. I wonder if all these work-up about my eyes reminded her that I haven't gotten the blood test done. I am waiting for another 3 weeks until i finish my intense Vit D therapy. What is going on????
