In pain 80% of the time? I had a kidney ulcer last year and i was in pain 100% of the time, throwing up and all sorts and didnt make that much of a song and dance taking sad selfies (although i did take some very weird selfies when i was given strong pain relief haha).Try and get a scan? I waited 2 months for a kidney scan during non pandemic time. She'll have forgotten about the pain by Monday.
She wants to be sick SO bad for attention whereas anyone who has had genuine kidney problems would have been more than happy to NOT have the attention....
