I have anal fissure gastroenterologist said it will take 12 weeks to heal I have a colonoscopy next week friday can this usually be fixed during it?

They are generally treated conservatively with stool softeners, laxatives and fiber, if not healing then there are medications and creams that can be used to relax the anal sphincter to promote healing. Last resort is surgery. ...Read more

Treatment for the anxiety issues through appropriate psychotherapy and medications if needed, can provide relief. ...Read more

You may get a colon transit study, anal manometry, defecography testing--to name a few. Pelvic retraining may help without drugs. Prostate checked? Had pelvic ct scan yet? ...Read more

Look inside colon: You are sedated (very sleepy, but still breathing on your own). The endoscopist places an instrument through your anus and then passes it into the colon to carefully exam the colon for polyps, cancer, etc. If any abnormalities are found a biopsy may be done.
