My Mother Slipped, Fell And Broke Her Humerus Bone A

My mother slipped, fell and broke her humerus bone a few days ago. We just got her home from the hospital late last night due to complications from blood pressure dropping and decreased oxygen levels. She is 89 and this has been very hard on her already. Just a bit ago we noticed her immobilizer was saturated with a mixture of clear fluid and some blood as if the swollen arm had burst. I cannot find its source, other than one little crack in her skin which is very thin and brittle at her age.
Trying to at least not take her out to a doctor until tomorrow because of how much energy it takes for her to do this...
