Hello, I have history of proctitis and I am on cansa suppository. symptoms with considering dietary choices like low fat diet and possibly avoidi stressor, symptoms -blood in stool- when get controlled. my 3 main questions are below: 1- is there alternative for canasa for times when I am away from town overseas for more than 6 months and this medication is not available outside except within USA.I used to receive oral tablet - internal coating but did not work for me. 2- does surgey helps in treating the condition because occasionally there are pusy discharges I find too when passing motion. I wonder if that wound in the rectal area needs to be cleaned like they do for any superficial wound with discharge in order to heal. 3- is there a risk for proctitis to develop to cancer because it keeps worrying always.
