I just finished the round of GI tests (excluding the colonoscopy). The endoscope showed gastritis from hyperacidity so we started treating that, but when some of the symptoms remained my GI jumped to the CT. When that came back clean my GI attributed the symptoms to IBS. To be honest, i think the worry of what might show up on the CT may have made my symptoms worse (apparently a good sign that it is indeed IBS). My mother-in-law has inoperable cancer, my father-in-law has prostate cancer, and my dad had both prostate & kidney cancer this year-- so the thought that he was checking for tumors was terrifying. Although I was frustrated at the IBS determination - it's such a nebulous diagnosis with no clear treatment- I already feel a bit better knowing that I am clear of cancer, no sneaky appendicitis (my sister, sister-in-law, & grandmother both had theirs out this year), or other issue. So although I feel a little silly to spend close to $2000 to find out that I have something that I already knew I had, I am glad that we did the tests. But I am fortunate to have VERY good health care and have been on short-term disability throughout this whole ordeal so I have had my full salary; if I didn't have those resources I would probably feel very differently about all the 'negative' test results.
