Can I ask what is a rhizotomy and what is it supposed to help or cure? I have horrendous “sciatica”!with S1 nerve and am almost totally bedridden from the pain on right side butt hamstring both calves and bottom of both feet. I walk about 15 min a day and then I have to go to bed and cry from pain. Thanks god for my wonderful husband. And thank you for taking the time to share.
