Based on my experience, unless you are losing or have lost the use of your leg(s) or bowel/bladder function, I recommend you exhaust all other alternatives before having such a radical procedure done.
I had what was described to me as a simple hemilaminectomy to relieve boney pressure on my L5-S1 nerve root in March 2021. 95% chance of an excellent outcome. This was not the case.
I rehab daily and my leg/ butt pain is still worse than it was before the surgery. Most days I wish I had not undergone the surgery.
No matter what the surgeon tells you, spinal surgery is a BIG DEAL.
Everyone is different. Some have the desired result but the vast majority do not.
Aside from the risk of infection, the trauma to the nerves will be extensive and if you develop scar tissue around the nerves, prepare yourself for a life of agony.
In any event, recovery is LONG if you’re in good physical condition and much longer if you are not.
I can’t offer alternative suggestions but I can tell you to be very deliberate about this.
