A disc bulge on an MRI is not, by itself, a reason for surgery. Imaging findings are common in people with no pain at all, and the great majority of sciatica settles with conservative care.
What actually helps
Decompression and directional-preference exercises reduce nerve irritation. Core and hip stabilisation restores the support the spine needs to tolerate load. Posture and workstation correction stop the problem recurring.
When injections are used
Where radiating pain is severe enough to prevent exercise, an epidural or targeted injection is used to open a window for rehabilitation — not as a treatment in its own right.
When surgery is right
Progressive weakness, loss of bladder or bowel control, or pain that fails a genuine course of conservative care are the situations where surgical referral is appropriate, and the recommendation is made plainly.
