Strange ongoing symptoms?

My sister has been bugging out and I’m on here to search for answers for her (plus I’m kind of annoyed at hearing about it all the time and I’ve never experienced anything similar, so I can’t relate lol). Over the past few months she has had on and off yeast infection symptoms, and had been treating them with monostat. She decided to hook up with a fellow and they had protected sex, but it was very painful for her so they stopped, but had (most likely) unprotected oral sex. Soon following, she developed uti symptoms, but apparently had been experiencing pain while urinating, so she was treated for a uti with medication. She still has not felt much relief, has had an on and off low fever, she feels very tired and now has developed spots on her tongue!

Anyone have ideas? She’s waiting to have her appointment with a gyno sometime next week. I don’t know how or if any of this relates.

Thanks for reading :) I’m just trying to be a good sis
