when will i feel normal again

its been about 5 weeks now since my fissure. on a high fibre diet since then. i have a skin tag now.

when i walk i cant stop thinking about the feeling in my arse. its so distracting. last week i felt great and thought i was fully healed. when id walk id feel nothing. no pressure , nothing at all.

but i had a pizza last thursday (gluten free) and some peppermint tea, and i couldnt stop farting all day. and the next morning i felt the discomfort again. im still getting normal bowel movements. but on days when i eat lots of sugar/cake, the next day i keep feeling in my arsehole that i need to go to the toilet. but i dont go unless i feel the urge. its really confusing. the past 2 weeks i was getting normal urges, id go once a day. but since the pizza day, ive felt this discomfort. been eating a bit more sugar than usual too, flap jacks, chocolate. i just want my bum to feel normal again without having to think about this all day long
