Sorry to hear of your diagnosis, but you've come to the right place for advice and support. I had open RH in lockdown last May, and posted a fair bit about my experience at the time. More recently, Cagney made a thread with some useful info too https://www.jostrust.org.uk/forum/cervical-cancer-%E2%80%93-treatment/preparing-abdominal-hysterectomy
I had to self isolate for 2 weeks before, which I don't think they make you do now? I had a covid test at a drive thru centre 72hr before and then I was admitted 24hr before my surgery, covid tested again, and isolated in a private room.
I arrived at hospital 8am Wednesday, surgery was 1pm on Thursday and I was discharged 1pm on Monday. I wasn't allowed any visitors throughout this time but the days passed quickly enough. I wasn't shy about taking painkillers and napped a lot of the time. My catheter came out on Saturday morning and I showered myself on Sunday evening.
My no1 tip and a few ladies here said it has helped them, is to get a Cushtie pillow, it was my best friend for several weeks, we were inseparable haha x
