Hi.
Read the history and understood your problem.
The burning sensation and swelling around the anus is suggestive of infection. This is usually caused by a small fissure to start, infection gains the entry and spreads around.
The fissures are small and your stools are soft , so the bleeding is not there.
The causative factor is usually
colitis with infection.
I would advise you the following:
-First of all to have a consultation of a Gastroenterologist for examination and a course of antibiotic,
metronidazole, probiotics.
Blood- complete blood picture,
kidney functions tests, blood sugar fasting and post-lunch,
Urine- routine,microscopy, culture and sensitivity ( before start of antibiotic)
Ultrasonography of abdomen.
High fiber diet.
Avoid all the foods and beverages and stress-like conditions which gives
constipation.
Laxative for softening the stool- never allow the dose too much to cause liquid stools.
Sitz bath- very important- just before passing a stool and after passing a stool.
Clean the area very clear of the fecal soiling that remains after cleaning; use cotton soaked in the same water to clean.
You can apply liquid
povidone iodine locally. Apply nothing else.
In most of the cases this works well and you will be fine.
Only rare cases need further evaluation if the medical management fails and you may need a specific treatment as decided by your Gastroenterologist.
