Well I have broken the rule. I got Noro once and it wouldn't go away. Literally 3 weeks later I was still throwing up every single thing I put into my stomach. I felt awful and after multiple ER and PCP visits there was no relief in site. I ended up in the hospital. I felt okay until I ate, and then I felt AWFUL. Spiked a temp, BP went up, felt jittery and panicked. Then I would vomit, but the other symptoms didn't go away. I was finally admitted and did ask my husband to please get into bed and snuggle me for a few minutes. Nothing relieved the symtoms I did feel a bit better when he was there holding me.
Now I walk into a pt and guest in bed often. Of course when they have been married 30+ years it is a bit more accepted. But I have also found siblings, adult children and good friends in patients beds. I never thought to be upset.
