pain
"I fell on concrete and they called it a chest wall contusion.  Fractures don't always show up on x-ray.  They gave me tylenol 3 because if I wasn't moving, I had no pain.  Well, it's been over a week and I tried to work my physical labor job...PAIN!!  This med hasn'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."
