Sounds painful, V. Did you fall?
Psychophant, I have also fractured a rib once. Took me a week to figure it out, though.
I have a tendency to go beyond my limits during sports and every now and then something happens(three minor things in the past three years).
Apparently its a stress fracture and it happened at the gym.
Doctor says its a rare thing but I should be more carefull next time.
Trying to find suitable alternatives to a gym for when I can exercise again.
Psychophant sorry to hear about what happened to you and thanks for your concerns.
