Apparently yes, you can!! At least I can!
I was in the floor (hands and knees) trying to coax Tigger out from underneath my bed. There is a table (like an end table) under the window that's beside the bed. I was trying to get up so I put one hand on the table and one on the bed.....just to give me some leverage.
I guess I raised my head up too fast because I totally lost any balance I had and felt myself going towards the floor.....but it was like slow motion. I could see the table and the bed.....and my walker parked right in front of me.
I bumped my head on the wheel of the walker and my arm on the table. Afterwards I just sat on the floor thinking "Only I could manage to fall when I''m already down on the floor"!!
I'm fine.....just a little abrasion on my knee and a small bump on my head. My arm is sore but feels like I exercised too much.........haha yeah, right.
