I am glad you found this site. I did also last year. Although my issues are cervical, I can relate to you. Ther will be others to help also.
Since you are so young, I would indeed get another opinion. Maybe with two different specialists, with your doctors direction he can help locate another. I asked my current Neurologist for a referral, even though he was the one who did my last surgery.
I was afraid too, to have a second surgery, much more complicated and serious than the first. This last surgery worked for me, and I am in a lot better place. I have less pain and NP, tolerable.
I am being lowered from Morphine right now. Yes it is possible to get off of all medication. I even got rid of my high blood pressure meds. Ask alot of questions, and gather your information, make the best possible informed dicision that you can.
Don't be afraid of another surgery, it can work out OK. You also have youth in your favor.
