"i fell on concrete and they called it a chest wall contusion.  fractures don&#039;t always show up on x-ray.  they gave me tylenol 3 because if i wasn&#039;t moving, i had no pain.  well, it&#039;s been over a week and i tried to work my physical labor job...pain!!  this med hasn&#039;t helped me much except for sleep.  however, i did wake up at times in pain.  too much tylenol can do liver damage so be careful not to take to much."
