We are extremely sorry for replying late, and since we don't know whether you got the required medical care and attention for your condition or not, therefore we will do our best to brief you on our analysis.
As you were operated for this condition before but it recurred, and also because you required an operation earlier to be able to cure it, therefore it's most likely a chronic type sciatica. If not, then otc medicines along with regular stretching exercises & walking must suffice.
For chronic type, you can get physical therapy, cognitive behavioral therapy (CBT) – which helps people with pain management by training them to react differently towards pain, painkillers, and as a final resort, surgery.

Surgeries are as follows:

i.) Lumbar laminectomy: widening spinal cord present in the lower back to reduce pressure on nerves.

ii.) Discectomy: either partial or complete removal of a herniated disk.

A surgeon will do the cost benefit analysis of each treatment and suggest you the best possible option for your condition, so to get in touch with experts, you should refer our page, they could help with second opinions too - Best Orthopedic Doctor in India.
