What are different ways to treat back spinal stenosis?

Physical Therapy: Physical therapy and pain medications (as needed) are appropriate first line. Spinal stenosis due to degenerative changes is relatively slowly progressive. If necessary, decompression laminectomy can be performed; but it is better to wait till it is truly necessary.

Injections surgery: Traction surgery is quite effectivewith low complication ratr for cental canal stenosis foraminal stenosis is trickier to treat.

Somewhat: There are a multitude of treatments for spinal stenosis which to some extent can "cure" the symptoms of spinal stenosis to variable degrees. For example, an epidural steroid injection can sometimes cure the symptoms of spinal stenosis for a long time, sometimes well over a year at a time. But with any treatment, the symptoms can return, even if surgery is done symptoms can return.
