You have my (son's) sympathy. He had major back surgery about 5 weeks ago, L5-S1. He is beginning to walk a bit and bend a little... fusion. He says the worst symptoms are absent. Carefully from day to day improving; can now drive a car briefly. Still occasionally taking a pain pill or muscle relaxant.
Many (FR) prayers have gone up. Steady progress - but the vertebrates have to grow together, like a tooth implant, it takes time. The surgeon said there was considerable damage.
Perhaps a course you should consider. Have you had any imaging done? A simple (cheap) x-ray is a good start.
