have had spondylolisthesis since accident 2006.3 surgeries:lumbar 2006, cervical 2013, thoracic T-12-13 2010. Never smoked-husband heavy and inconsiderate smoker, alcoholic. New orthopedic spine surgeon has put me through CT scans & several MRIS-----advises that osteoarthriric spine soon requires further surgery in all 3 areas. I ve been having violent, sudden falls-1 concussion 2015. Surgeon considering further lamination, fusion. decompression with therapy. Had COPD exacerbation May 22 this year with 2-week hospitalzation. PCP & Pulmonary Specialist treating me must manage my COPD before Dr. Kerner will operate on me. What causes nausea and fatigue, sharp headaches at temples--new symptom? Thank You
