I did something similar last week but not as bad as yours sounds. I was leaving DD's doctor's appointment and headed down a hill with my purse on one side, grasping DD's new fire helmet (smokey the bear gave it to her) and pushing her umbrella stroller. To make a long story short, I tripped against her stroller, fell to one knee and twisted my left ankle. Bright spot was I didn't lose my grip on the stroller and so DD didn't fly off down the hill! I went home and iced it with heat alternatively. Took some Tylenol (since we are trying to get pregnant) and elevated. It is still sore, but only if I move it from side to side.
Mental note: Next child, I WILL get those extenders for the stroller handles! Umbrella stroller handles are too short for someone that is 5'10", I'm always tripping over her wheels.
"You know I was talking to my friend Desdemona the other day she
runs this space station and bake shop down near Boomtown. She told
me that human beings are flawed individuals. The cosmic bakers
took us out of the oven a little too early. And that's the
reason we're as crazy as we are and I believe it." Jimmy Buffet, Fruitcakes, 1994
