Think very carefully before surgery. I recently read a book on pain by a back doctor ( I have pain issues of my own, tho not back pain). He had had to accept the fact that many back surgeries are not needed. He started treating his patients for pain, giving them the tools to reduce pain without surgery. Many people found they didn't need surgery, those that still did had a better recovery.
His point is that everybody over a certain age has some adaptive damage or changes to the spine, yet some with the same spine issues have no pain, so it is not these changes that cause the pain, rather it is a matter of pain processing problems.
I am out right now, when I get home I will tell you the name of the book, it has been very helpful to me, I stropped pain meds three weeks ago, after seven years on them.
