I had back surgery in 6/08 for a flat back,since then I can t walk alone. I Had 2 spinal tears had to stay in NEURO ICU FOR 7 days, left ankle in on a ball no stability 360 degrees. Cyatic damage in left hip. Was told you wanted a curve in waist so that is what I gave u. He would not fix disc unless I let him break my back, still bent over.
Here I understand you have damage in spine with spinal curve loss as well you was operated in 2008 but since then the issues are more and now there is no stability with left ankle as well you also have issue with left sciatic nerve. Here I suggest you visit spinal surgeon for secondary opinion and then also take suggestion from a good physiotherapist. Here based on current physical evaluation and report they will suggest you conservative management with physio treatment to heal the soft tissue and strengthen the back muscles. Also, may need to do some treatment for ankle instability and sciatic nerve pain. You can also use hot and cold pack on your back for some more relief and reduce inflammation. For major issue like soft (annular) tissue tear(major) you need to go for surgical repair or immobilization of spine for giving it time to heal. However the treatment will be suggested by spinal surgeon only. Here I suggest you can also take opinion from two different spinal surgeons to have proper idea on safer treatment planning. Here I have given you general guideline since I am not able to assess as well see all your past report. But I suggest following it step by step, and I am sure his will be useful for you. Take care
