Hi i have a sentinel pile, it started paining since 3 days, now its swollen n wen i observed in mirror i saw a pale yellow swelling on it. wat is it?

Sign of anal fissure: Sentinel pile is a sign of anal fissure , will cause severe pain , constipation , associated with small amount of bleeding during bowel movement . Swelling is due to associated inflammation , eat high fibre diet , stool softeners , plenty of fluids and local care , most of the time will heal in few wks , chronic painful non healing fissure will need minor surgical procedure.
