Just returned from the hospital..... Answered
Last night at work, I started having chest pains and pressure, and so spent the night in the hospital getting it checked out. AFAIK, it turned out not to be heart related, but they still want to run a stress/echo-C test just to be sure. At this point, we are not sure what caused the pain/pressure for 14 hours. But it is good to know it is probably NOT my heart :-)
ADDENDUM: .the Heart Cath, prep and procedure take up much of a day's time (started at 10 am and got out of the hospital by 4:45 PM). And I was completely wiped out mentally and physically by then.
All went fairly well, they found one artery about 70% clogged but not enough apparently to need a balloon or stent (shrug), so I will be "watched" for awhile. So, thankfully, no "extended" stay at the hospital this time around. I will be going back to work in Monday even.
