Got pain on my left side a few inches below armpit; worse when I inhale, sneeze, laugh and when I press on it. Had a fractured left rib a while back?

Rib injury. A rib injury can cause all the symptoms you describe. It's possible to crack a rib with a strong cough or sneeze! Treatment of a rib injury is limited to pain medicine and sometimes taping of a small area of the chest. Important to do deep breathing exercises or use an incentive spirometer to prevent a lung infection in the side of the pain.
