Having sinus surgery July 5th. Anyone know if I can still caregive?

Mom is 93. Needs depends changed -
Meals made, bed changed daily. Baths 2 x week
Unless other issues crap up
I'm to have no physical activity and will have polyps removed, balloons in nose
For several days and bleeding. Will it be possible
For me to give her proper care?
She said she'd take care of me, God bless her.
I really don't know what I'm getting to. Anyone been through this or know someone who has? I have been laid up with sinusitis for mints now.
