Rectal bleeding for 5 months, sent to GI doctor. Told its normal for IBD patients. I asked if its hemorrhoids, they said unlikely. I dont know where the bleed is, isnt anyone supposed to physically check to see if it is hemorrhoids or something else?

It depends... Apparently you mean IBD (inflammatory bowel disease, i.e. ulcerative colitis, Crohn's disease), not IBS (irritable bowel syndrome). IBS doesn't bleed, IBD often does. Need for internal exam (e.g. proctoscopy) depends mostly on amount of blood, changing symptoms, etc; maybe no need if no recent change. This sounds mostly like a doctor-patient communication problem. Ask again or get 2nd opinion.
