I FELL GETTING OUT OF THE SHOWER 12 DAYS AGO.

I FELL GETTING OUT OF THE SHOWER 12 DAYS AGO. HIT MY BACK ON THE RIGHT SIDE AGAINST THE CABINET. NO VISIABLE BRUISING. HAD CHEST XRAY DONE, NEG FACTURES, UNREMARKABLE. PAIN CONTINUED SO DR. ORDERED CT SCAN WITHOUT CONTRAST. WAS TOLD THAT WAS UNREMARKABLE ALSO. pAIN HAS INCREASED IN SEVERITY. HURTS TO TAKE DEEP BREATH.
ANY IDEAS ON NEXT STEP TO PROCEED IN FINDING OUT WHATS WRONG. PAIN IS FRONT RIGHT CHEST WALL, JUST BELOW BREAST AREA.
