Dear friend , if conservative measures are not helping, modern spinal microdiscectomies come to help. If an expert is advising surgery, then in good surgical hands, at good high turnover centres, discectomies could help, esp. if you have distressing neuro signs.
I am not a spine surgeon
. but looking at the results of surgeries at our centre, I think they should help you.
I would advise you to go by your specialist's suggestion.
thanks for being at HCM and hope to keep posted on your progress.
