Lumbar facet syndrome on left side. Small rounds lumps that are movable in same area. What are they? Spine also has bump I can feel in bone.

Facets. The lumbar facets are deep in the back on the lateral portion of the spine. They can not usually be felt . What you do feel may be some isolated areas of spasm. If the bump you feel is in the center it is the spinous process of the vertebrae which sticks out and I'd readily felt.
