Itching butthole driving me crazy, any tips?

Hey, I got diagnosed 6 months ago and have probably had UC for 2 years, recently my butthole started itching so my doctor told me to put some vaseline and try to wipe more gently. The vaseline helps a bit maybe 5 percent but doesnt solve anything and every day for a month the itching has gotten worse from barely noticeable to today making me go crazy, trying to not scream. Does anyone have any tips or advice or something. I dont know what to do.
