I am very interested in this also because I had cervical fusion in December 1998 and then L5 S1 laminectomy in March of 1999 My pain is returning and getting worse every day. In fact I am going to my doctor today to see if she will order an MRI because at night when I try to sleep it is unbearable. I wake up so much because when I try to change positions it is SSSOOOOO painful. The daytime is better but not great. If you find out things about this I would be very interested in hearing from you what you have found out.... Thanks so much!!!!
