Have posted already but no answer so hopefully someone might know, does rectal nsaid cause bleeding, had bright red blood on toilet paper and then dark stringy blood in stool the following day. No further bleeding except mucus for a day after, sorry gross information. have lower back pain a few weeks and was taking medication for same, couldnt tolerate oral nsaid so used 2 suppositorys on 2 consecutive days. Bottom doesnt feel sore so i dont know whats going on. Seeing doc tommorrow but would like some reassurance, have had awful diet for years and never had any type of screening for colon cancer am 33 years old, dont have regular bowel motions for a long time and get diarrhoea if i eat two much fruit, thanks for your time,
