Not new to back pain and was member during and after L4L5 fusion in jan 08. Recovered well and had r shoulder replaced Dec 2010. I fell on steps (landed on rear on edge of step) Feb 9 2011. was diagnlosed nondisplaced sacral fractujre and sent home with no activities to avoid. That eve my right leg gave way and I fell again landing on r hip.excrutiating pain landed me back in hospital. CAT done and no further injuries reported. 3 more months of agony and I was referred to neurologist. Fracture of right pelvis and right hip found. I had been walking etc and suffering all that time. now L5S1 stenosis also a problem. A week ago my right ankle and foot started to swell with fluid and terrible nerve pain.My left to lesser degree. Now the skin is mottled red & purple but not hot and no fever. also ultrsd done ruled out clot. Has anyone had this happen as a result of this type of injury? ER Dr baffled and don't see ortho about repair to pelvis until later in week. I appreciate any input.
