Thanks to a conversation I was having with an ex-police colleague the other day, I've now developed a fear of dying on the toilet if I strain in any way - and earlier, I thought I had a pain in my right temple and then eye after I 'went' and it's now freaking me out.

Whilst the bowel urgency I've suffered from for years seems to have passed (the metformin and simply drinking loads being the culprit), this is a new worry for me and I wonder if anyone else has had this fear?
