cyane, if a fissure is what is causing your blood then here is what i did to heal the fissure that bothered me.
i got high quality coconut oil, food grade. then i applied some directly the area before and after every bowel movement, generously.
then i made some small torpedo shaped coconut suppositories. its easy, just let the coconut oil get soft but not too soft then form them by hand, then put them in the freezer. once frozen solid you can use them.
before going to bed insert the coconut oil suppository like you would any suppository. all night long the coconut oil will work to heal the fissure. do this everyday for a week or so and you will see great improvement.
