This is apparently a “complication” from my previous back surgery - cleaned up the bone to give my nerves room to do their thing but the vertebrae started sliding out of place at the end of 2021 and got worse at the beginning of May.

The plan is to fuse the bottom 4 vertebrae together because, according to the new surgeon, if he doesn’t I’ll be back on the table again within a year. He also claims I’ll still be able to ride but I strongly suspect this means the end of trying to do better every year and there might be a recumbent e-bike in my future.
