Could I possibly have Spinal Epidural Hematoma? I had an anterior/posterior fusion at L5-S1 in 2010. Felt relief for a few years. Had a gradual onset of pain in lumbar & right lower extremities.MRI 2013-extrusion at L4-5 & small disc buldge at L3-4. Surgeon went through preventative treatment (e.g. physical therapy, injections, anti-inflamatory & muscle relaxer meds). Eventually decided XLIF at L4-5 performed January 9th, 2014. Upon recovery I felt worse. Increased back pain & lower right extremities. After months of pleading underwent EMG/NCS, MRI & CT. MRI could not see right neuroforamima due to hardware. CT showed possible fluid, infection & now indentation of thecalsac. Orthopaedic Surgeon schedules surgery 1 week after new findings. Now May 15th, 2014 undergo surgery to correct thecal sac indentation. Once I awake from surgery while laying on my left side (right side still very tender from XLIF in Jan.) I abruptly flip to my right side as left side becomes unbelievably painful. First time, the onset of leg tremors. Uncontrollable painful violent shaking in both legs. Undergo more imaging, still a buldge at L3-4 & decreased height in L2-3 & now a small anular tear in T-11/12. In addition I am experiencing high heart beat. Neuro called in by my Ortho, orders MRI of brain (nothing abnormal) ultrasound of both legs(extremely high heart beat in both). Since the last surgical attempt I have chronic radiating.pain in both feet,calves & thighs. More debilitating in right legs.
