Hi Fizby-
As JJ mentioned, the sympyoms of lumbar stenosis can be hard to distinguish from MA symptoms. Both stenosis and MS cause problems with nerves that control the legs. The good news about stenosis is that, unlike MS, in many cases it can be fixed.
I had a lumbar laminectomy which reliever the pressure on the nerves in my lower spine. This relieved many of my symptoms. The bad news is that my MS marches on :-)

Hello fellow Ozzie, i'm not sure if you are aware or not but your question has landed in the MS community and whilst people with MS can also have other conditions too, the symptoms of MS are caused by brain and or spinal cord lesions.
Although sometimes symptoms of different spinal conditions overlap or can be very similar, MS is very different to stenosis and has only a few similar treatment options ie physio. Stenosis related information that may be of some help.....
"Lumbar Spinal Stenosis
In lumbar stenosis, the spinal nerve roots in the lower back become compressed and this can produce symptoms of sciatica—tingling, weakness or numbness that radiates from the low back and into the buttocks and legs—especially with activity.
Lumbar spinal stenosis often mimics symptoms of vascular insufficiency. Both conditions can cause claudication, which means leg pain with walking. If vascular studies identify normal blood flow, and there is confirmation of spinal stenosis on diagnostic testing, the symptoms are then called neurogenic claudication. In the classic description, people with spinal stenosis will describe an onset of leg pain, or weakness with walking, but with relief of symptoms with sitting. Many will also describe increased tolerance to walking when flexed forward, such as when walking while leaning forward on a shopping cart.
While lumbar spinal stenosis most often occurs at the L4-L5 and L3-L4 levels, it can occur any level in the spine. The degenerative cascade may eventually effect most of the vertebral segments of the lumbar spine."
