I am a Multiple Myeloma cancer patient with high risk factors and had a Bone Marrow Transplant at Mayo Hospital here in Jacksonville, Fl, in September 2020, in the height of Covid.

I was hospitalized for 13 days, during which time my sister stayed with me. She slept nights but would leave during the day to do her personal stuff and shower, change, eat, etc. She slept on a pull out hospital sofa-bed, which she said was comfortable. She didn't use my bathroom but one on the Transplant floor. She wore a mask around me except when she slept.

Having her there was helpful, although the Transplant nurses was right outside my room.
Because of all the drugs during the various phases of treatment, I started to experienced a sense of urgency to go to the bathroom. At night, the nurses put on a bed monitor that locks down the bed and if you try to get up it would set off an alarm.
Because she was there they agreed not to engage the bed alarm.

She also ordered all my hospital meals for me.

There was an exercise bike in my room and others on the floor of the Transplant Ward.

There is also a TV and phone wall jack to charge your phone.

The nurses bonded with her and said that it is evident that I will be released into excellent care at home.
Because I live 15 minutes away from Mayo Hospital and was doing really well, I was released just 13 days after transplant.

Hope your dad's journey is an easy one. I wish him and you all the best.
