Thank you so much for the kind responses. It turned out to be iritis and the steroid drops that I started yesterday evening have already relieved much of the pain. Just in time for me to prep for my colonoscopy tomorrow!
I try to keep a pretty good attitude, but boy this disease will really take you for a ride and test your spirits. It's at least some small comfort to have the kind people here on the forum to- -cry, whine, bounce ideas around --with.
I wish all wellness today, if not in body then in spirit.
