Ok, well. It's good that there's no blood today and it's more solid.
HOWever - and I know this having spoken to both GP and consultant about it for about four months, a few years ago - I'm a nervous patient! - having bleeding and mucus in your stool is NOT normal, it's never normal and this with the pains you've been getting strongly indicate bowel inflammation.
Your bowels don't inflame for no reason. It could be ulcerative colitis, or Crohns disease, or another inflammatory bowel disorder. It could also be infection - possibly a nasty one like I had, well, almost certainly a nasty one of some description
There are some types of food poisoning that cause this too.
I don't care if it's stopped for now, you really, seriously need to go and discuss it with your doctor as soon as possible.
Old people often die from c-diff, so you need to rule that out. Cohns can become very serious as can UC and you don't want it to end up being an actue situation, rather than the rumblings you have had so far which can be controlled fairly easily.
I'm talking about it getting a whole lot worse if untreated. So there is a good reason to go in NOW and at least have some tests done, or be told what to look for in terms of symptoms.
Honestly please don't take a risk with your health. There's a reason for this - hopefully NOT pseudomembranous colitis but really, it all needs checking out.
