Itchiness around anus after pooping.

For the last few dayslike 10days, i was facing itchiness around my anal area just after completing bowel movement. And for the last 3 4 days, i am not facing itchiness but slight uncomfortable  sensation like slight burning sensation there after pooping but there are no symptoms  during pooping , only occurs just after pooping and washing that area .Also does not occur at other times of the day. No blood, no pain nothing. I used hemolit ointment for last 5 6 days just after pooping 2 times a day. As soon as i applied, it used to relieve me . For last 2 days i am not using hemolit and using tbact instead. It is also relieving me and I also took ivoral forte yesterday.But in these last few days i noticed that whenever I dont use any cream I face itchiness or lil burning sensation. I apply the ointment by finger so there is no lumps or any cuts inside the area. Can it be dermatitis or bacterial or yeast infection?  Please suggest something.
