"You should never, ever get back surgery" sounds like that easily could be wrong. It's annoying to have to always caveat but talking to a (good) doctor is important when making such decisions and not relying on tech forum advice necessarily. I know someone who said they went in for back surgery and walked out feeling permanently cured from the specific problem they had and the pain was completely gone. Details matter. Always consult experts when possible.
You left off the 'if you don't need it'. Even back specialists will tell you that surgery is typically the last resort because of the risks of not fixing the issue and/or making it worse. It's not like fixing an ACL.
