hi dr i am not sure how severe your husbands symptoms are lets face it the most definitive treatment for this is surgery but i would never suggest that as the first line treatment unless the symptoms are exceedingly troublesome what you could try is a. regular lumbar exercises b. avoid lifting heavy weights and bending forwards c. maintaining your posture as you sit in a chair (anaysis) d. lumbar belt would help you e. tablet methycobalamin once a day (its a special vit B that helps he nerves) f. tablet pregabalin 50 mg once daily. it can cause drowsiness and vertigo. if that does not happen, you can step up the dose every 15 days (25 mg at a time) till a dose of 150 mg twice daily frankly i would suggest you meet a physiotherapist too they can really help but meet an orthopedician before that i am sorry to be of so limited help but online help literally rules out examination hope this helped best of luck
