Hi lorie. I am not waiting long for a ct scan.... I have been having one every 3 or 6 months since 2011 and have had 2 surgeries and 2 rounds of radiation. I just saw a cardiologist last month for a checkup at mayo. Everything was good. I think I am covering all the bases. My gp is setting up an appt with a neurologist here and if it shows something serious I am heading back to mayo. Thanks for your help and caring.
