Hi, thank you for posting.
I have gone through your query and I understand your concerns.
I think that you might suffer from a digestive system infection such as Candida albicans.
This infection causes the same symptoms as colonopathy and it can also cause hemorrhoids.
The above conditions can weaken anal sphincter.
To confirm the diagnosis you need a stool culture, abdominal ultrasound
, fibrorectosigmoidoscopy and a complete blood count
All the best.
