Morning for me and this is just me I have a fusion on L4/L5 which is just above the sacroiliac joint. I don't know if it's because I'm thin or just the position of it the fusion but I feel it all the time. On the other hand, I would never consider a spinal cord stimulator you never know what could happen or go wrong heard too many stories about the SCS. I've also spoken to people with multiple fusions and they have absolutely no problem at all. If I were you no matter how long you have had this surgeon I would get 1 or 2 more opinions from surgeons to look at your back and see what they say. It's a matter of opinion and what you feel comfortable with but do the trial SCS before you make a permanent decision. Again this is my opinion only and you are the only one that can ultimately make the decision for yourself. I'm sorry I never went for another opinion before I let this surgeon do the fusion. I had a herniated disc which could have been handled quite differently. But I found out that my neurosurgeon does spinal fusions 100% of the time. Good Luck my friend.
