Steroid cream - yay or nay?

I have seen mixed reviews on here about whether or not to use a steroid cream. My itching is really bad and I was prescribed Betamethazone Val 0.1% by my doctor yesterday. I have seen some people mention that the rash came back worse after stopping the steroids but it’s hard to say if they meant oral steroids or a cream. If you used a steroid cream I would love to know how it went for you. Thanks!
