Hi, I agree with Leesa, I've read that within 11 years after a spinal surgery, a person will more than likely require another surgery due to the stress put on the upper and lower levels. I had my first fusion Feb 22nd of this year, I expect that more than likely, sumwhere within the next 11 years, I'll require another. Its a roller coaster ride, one I can't relate to yet. Take care, I wish u the best!!
