Scary nosebleed!

I had an extremely scary experience last week, ended up in hospital for three days with a nosebleed.
It started when I was in the shower and was pouring, it would have been funny if it wasn't for the fact that I was on my own, hair covered in shampoo, trying to hold nose, rinse hair, get out of shower without leaving a trail of blood, wrapping yourself in a towel singlehanded is no mean feat- , trying to keep calm was hardest bit (I am a nurse and have dealt with many serious situations, but when it's your own blood it's kinda different)
I managed to get to my phone and phoned my friend, who luckily was passing the door, she was a saviour, she kept calm throughout, drove me to GP then A&E, where it was pinched with clamp, and a thing like a nose bag, very dignified- eventually tried cauterisation which after 4 1/2 hours seemed to work, but oh no, after being at home an lying on sofa for couple of hours, the flood gates opened again, far worse than before, and I was near panic stations, my partner was trying his best to keep calm, but I could see the 'rabbit in the headlight look' as he said 'it's ok you'll be fine'
Anyway further trip to A&E, more pinching, cauterising to no avail, at last attempt at cautery it made things worse and even dr called for help!
My nose was then packed what felt like a torpedo, it is a tampon like device that is inflated to stop bleeding, ice pack on my head, cannula inserted in arm and more bloods taken.
I was then admitted to ward where I stayed for three days, saw ENT specialist who took pack out, I was scared to move, he did more cautery, which seemed to do the trick.
I was then given a long list of what not to do, breathing seems ok but everything else is taboo!
E.g. No hot food or drinks, no bendng, lifting, stooping straining, nothing strenuous (?)
Bed rest for 48 hours ?, do next to nothing all week...
Who said nurses make bad patients........?
