Hi and welcome. if your talking about those bumps on the cheeks they are not hemerrhoids. Bumps could be anything and we would be guessing. I think best to see a dermatoligist if your worried
If you also talking about the peice of skin at the bottom of your anus, that looks like a hemorrhoid
you must see your doctor for expert advice, hopefully you are not getting hemorrhoids, if you get it use Lido-Nifedipine Gel to cure hemorrhoids, very effective to cure hem.
