Patient: Hello. Thank you for helping me. I am 16 years old. When I was 11 I had a lumbar fusion on my L5S1. Since that surgery, I have had problems. The year after my big surgery, I was in a wheelchair for almost a year, not being able to feel my legs. Then two years ago it happened where I couldn’t feel my legs for 5 days. It happened last year too. It would happen when I would run or overdue my back. Three weeks ago I hit a volleyball. My back instantly hurt at my surgery site. The pain got worse by the minute. I sat down in a car and my legs went numb. I was hospitalized for over a week and didn’t get my feeling back for 11 days. Today my back hurt and I sat down and lost feeling. I worry my nerves keep getting worse. It’s been going on for 5 years. No doctor can figure it out.. Any suggestions on what it is?
