I am having minimally invasive spinal fusion on L5-s1 also a large annular tear- I am having lots of pain due to the sciatica also. I am afraid- the surgery is on 1-15. I pray all goes well and it helps! I've had fibro. for about 5 yrs. The stress of upcomming surgery has had me in a alot of over-all pain the fibro is flaring. Nothing seems to help right now. I maybe sleep 4-5 hours a night.. I take bupeprion & hydrocodone for the pain it does not help much. I don't want to be so down- Has anyone had this type of surgery? Did it help?
