Sounds like a fissure. Not a big deal, millions of people get them.For most people, they come and go. For some, they become chronicand these may require surgery. Also, infected fissures may cause a perianal abscess. And 50 to 67%of the time, an abscess develops into a fistula and this almost alwaysrequires surgery. Don't freak out as the fissure most likely go away. But if you have excessivediarrhea or constipation, it may become chronic.I have two currently, and it may have caused my perianal abscessesand fistula. The treatment is a nitroglycerin cream but this causes severe headaches anddizziness so the top colon rectal surgeons now prescribe diltiazem.Other possible treatments are botox and fissurectomy.I recommend seeing a colon rectal surgeon.
