There has been no odor other than when I release the pent up gas. As to embarrassing moments, they say that anything that doesn't kill you makes you stronger. I really now believe that more than anything. I could have let this disease cause me to die because I was too embarrassed to say something in the first place. And I'm spreading the word to get yourself checked.
Early detection is critical.
I sincerely hope that this has provided some useful information. I wish that there had been someone I could have talked with before I had my surgery. My anxiety level was very high beforehand, but over time I'm really glad that I had the surgery. My only regret is that I didn't mention the blood when I first noticed it so very many years ago. At that time it may have just been a polyp, so easily removed.
