Hello, I am a healthy, fit, 39 year old male. I was diagnosed with a herniation to L5, through an M.R.I., and consultaion with orthopeodic surgeons. The question I have, is that I was informed, as I have no specific point of trauma to my back, my disc herniation was due to normal disc degeneration. I am in excellent shape, physically active, and work in the construction industry. My job involves very heavy work, extensive twisting, and articulating of my joints. I feel that my employment duties directly caused my affliction, and that it is not "normal" for a 39 year old healthy individual to have a herniation, and a micro-discectomy scheduled within 2 weeks. Am I mistaken? Is this normal, or could my employment have caused or exasperated this condition? Your feedback would be greatly appreciated.
