Vick, I would call the doc....it may be something, but it sure warrants being checked out just in case. Even if they do not really treat a rib fx, it is worth it to know if you actually have a fracture or or a pork chop bone. I vote for the porkchop bone...
And don't beat yourself up over this, not like you had any control, so it is not fair to call yourself a dope!
Vicky: I agree with the others that you need to call you onco and let them know. I never broke a rib but have had them out of place numerous times...coughing, falling, etc. I go to a manipulative therapist (one of only 3 drs that I would put on a pedestal) and she is able to get them back in place..but she does it very, very carefully. Switching from ice to heat helps w/ the pain.
The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly."
