I am a 60 year old male. For the past few weeks I have had bleeding skin around my anus. I thought it was bleeding hemorrhoids, but it continued to get worse. I had my wife looked at it and she said a large area of skin around my anus and far up my crack is very red. There are no bumps. It does itch, but hurts if I scratch it.  It rubs and hurts as I move around. I have been using a warm sitz bath for a few days but it is not helping.
It could be anal fissure or tear, due to constipation and forceful defecation, kindly try site bath. It is done by siting in a tub full of lukewarm water and add KMNO4, or if KMNO4 is not available then simple lukewarm water. You can apply locally an ovate cream, and start eating high fiber diet which will soften your stool.
