Update:  Dr.'s office called yesterday.  All clear on the CT scan.  Great news.
Today I had what is to be the first of three iron infusions.  The entire procedure took about three hours and was given through my picc line.  After I was finished my Dr. showed up and showed me just how badly I needed this.  He pointed out that normal iron levels are between 30 and 300.  Mine was 4.  Infusion number 2 will be in two weeks after which, he explained, I would start feeling much better which I take to mean more energy.  In fact, I already feel a small difference in my energy level after today's infusion.
Two weeks tomorrow is our Walk/Run for Scleroderma.  Time to start praying for good weather.
