Long term lifter and runner and have experienced periods of lower back pain over the years. Typically I am able to scale back for a time, recover, and get back at it. At 40, I have not been able to recover as before. During an SI and L5 vertebral facet cortisone injection the doctor noted some arthritis. I have recently joined a crossfit gym and am now looking for information on managing the arthritis. Has anyone dealt with this? Any thoughts or guidance is appreciated.
