I have a 9mm extruding disc at my L5 S1, causing indentation on the nerve roots. Over the past 3 years this extrusion has calcified. Recently I have had tingling and numbness in my left leg, with occasional severe shooting pain. Is physical therapy an option for dealing with a calcified disc fragment that is sitting on a nerve? Or is surgery my best option? I ve been told that the calcified fragment isn t going anywhere without surgery and will only get larger over time, which will cause more symptoms. Thank you for your input.
