Discopathy l5-s1 and sciatica,what can go wrong if i have surgery,what is the risk?

LAST OPTION!: Surgery is the LAST OPTION, unless there is a clear, well-documented, and progressive loss of muscle strength in the leg / foot ("foot drop") The most common outcome of disc surgery is incomplete pain relief. Other risks are infection, never root damage, chronic severe headaches, progressively more severe back pain, air embolism (which may be deadly), and complications of anesthesia.

Speak with surgeon: He should be able to address your concerns after surgery.
