Hi.
Thanks for your query.
Noted the history and understood your concerns.
It looks that you have holes near anus and not in the stool, also have itching and thus I would advise you the following in such a situation:
Consult a General Surgeon for clinical evaluation, examination, per-rectal digital examination, ano-proctoscopy and plan for
colonoscopy.
If this is due to fistula in ano, you need a
biopsy, fistulography and surgery along with biopsy of the specimen for getting the correct diagnosis for getting a specific treatment.
If there is no specific cause that can be found surgery still helps.
But there is no fistula but perianal excoriation then the obvious treatment is a course of an antibiotic,
metronidazole, probiotics and local application of liquid
povidone iodine after washing with copious amount of water and keeping the area dry; avoid tight clothes and hot, humid atmosphere.
