I dropped a steel ramp for a trailer on my left foot about 10 days ago and it was not broken. I have been careful with it, but suddenly the pain in excruciating and I have more of a red discoloration to it. When I first dropped the ramp it was not even black or blue in color. The foot only swelled. How long can it take for this to heal? Should I see a Doctor about it or will it heal by itself.
Hi, I understand your query & concern.  The problem you are describing along with severity & developments that had followed, indicate a fracture of small bone in foot, following the fall of steel ramp on your foot.  The immediate reaction was swelling of the foot, & pain started as the fractured segments were disturbed & moved. Left untreated it seems to have turned in infection / cellulitis that's why the redness.  * I would advise you to get urgent advise of an Orthopedic Surgeon & get X-ray & blood counts, blood sugar done to start with the specific treatment as per his advice.  Thanks.
