hi , i have been having stomach problems for a long time now , gall bladder and appendix have been taken out . now i have a problem my doctor can not figure out , rectum burning itching and pain no bleeding , more burning than anything. it gets worse the more i do , like work or walk a lot , also the more i use the restroom the worse it gets ...mornings after a good nights sleep i am fine until around noon , i have had a colonoscopy , endoscopy , cat scan blood work and many meds....to me it feels like its muscle or nerve related , hard to live a normal life or just get comfortable . he has me on a rectum cream now that relieves me for an hour or so.also i cant remember what its called but when i move my muscles in my rectum it burns also... do you have any ideas i can have my doctor check
