I have developed a small ulcer like wound about 2 mm dia very close to the anus. It has a stinging pain when touched. I had had a perianal abscess operation over a year back. Later after it had healed a red dot like swelling remain and he said it was a fistula. I went for Ayurvedic second opinion and the doc said it not fistula. It didn't bother much later. Now is this present white dot like wound linked to the earlier incident ?
