In the past I could, and did, live with diarrhoea, anything up to 10-12x a day. However I didn't have proctitis back then and I didn't realise how awful that made things. Also I still had a colon, so BMs weren't like battery acid, the way they are now.
Small amounts of blood don't perturb me. I'd have to see a lot of blood in the bowl before I really worried about
The main no-go symptom for me is pain. It eats into your sleep and is seriously detrimental to quality of life. It forces me to eat a bland diet, which I hate. I dream of large bowls of crunchy salad - my child self would have thought I was nuts. And, yeah, I miss nuts too.
I don't mean to be rude, but if I had your symptoms, I'd frankly consider myself in gastrointestinal heaven. I'm slowly coming to accept that my digestive system is borked for life, no matter what I do from now on. That said, I know anxiety is a funny thing and you can't help how you feel.
Dx Crohn's in summer of 2000. (Yay )
Tried and failed: 5-ASAs, azathioprine, 6MP, Remicade, methotrexate, Humira, various diets.
Had surgery Feb '13 - subtotal colectomy with end ileostomy. First thing to put me into remission in 13 years.
Had second surgery 10th July '15 to reverse the stoma and connect the ileum to the rectum. Officially flaring again. The fun never begins.
