Hope your doctors appointment went ok, ... Its always possible a hemorrhoid has been missed but when you have the colonoscopy the gastroenterologist will be able to check you thoroughly so you won't be left wondering what's going on. I know it's easy to say but try to put second guessing to the back of your mind and wait for the scope to be done. Write a list of any questions you might want to ask such as the possibility of food intolerances should your results still come back as normal. ( hopefully they will be normal and diet is the answer ) lets know how you're getting on
I have an appointment again tomorrow. I take probiotics, and have noticed that drinking milk makes it bad. Is it possible for the doctor to miss internal hemorrhoids with a finger exam? I had that done two weeks ago. Just wondering.
Possibly an anal fissure? It is also possible that there's hemorrhoids causing the problem.
In the meantime of waiting for your tests and diagnosis it might be worth trying a good probiotic and drinking cranberry juice. Anti biotics can kill off the good bacteria , certainly worth doing. If tests come back normal ask if crohns and celiac could be an issue.
Best of luck
