I’ve had 3 major low back surgeries. Hip replacement as well. All my joints need replacing. Find yourself a spine pain interventionist. Or a good orthopedic or neurosurgeon.
You need x rays and a MRI.
Most likely they’ll suggest a series of injections. Either cortisone for inflammation or a pain reliever. If that doesn’t provide relief the next step is getting pain nerve ablations.
The Dr cauterizes the pain nerves that go to your brain. If you have extensive damage to your back the next step is a spinal stimulator implant.
It’s a life changer. It has eliminated at minimum 80% of my lower back pain. Physical therapy is an absolute must. You have to strengthen your core. It’s a forever thing you must do at minimum 3 days a week.
