Spinal stenosis: The technical term for what you have is called degenerative lumbar spinal stenosis and it is an arthritic condition. It can be asymptomatic or can cause problems with prolonged standing and walking. Patients will often lean forward when they walk and you can often see them at the store leaning on to a grocery cart. Many good treatment options available, don't hesitate to be seen.

Dr Rhoads and another doctor agreed

Spinal Stenosis: The symptoms of back or leg pain with standing or walking are known as neurogenic claudication and should resolve with sitting. The spinal canal narrows when you are upright and improves with forward flexion and sitting. Minimally invasive decompression procedures that enlarge the spinal canal are very successful and, without instability or deformity of the spine, fusion is not routinely needed.
