During the excretion of stool i always feel a sharp pain in my anus. Its been 4-5 years. Earlier i only had pain so i ignored it. From past 1-2 year i felt a bit of skin growth on the outer part of anus. And now from 1 month whenever i go to bathroom stool comes along with blood from that skin. I visited surgeons and they said that its anal fissure and prescribed medicines(a cream to apply+one syrup to drink at night+some tablets). But i havent seen any improvement in shrinking of skin. Suggest
