yes. the nerves in your body all go to your spine, then to your brain. if this nerve intersects with L3 OR L4, it will inflame the disk. the knees' nerves correspond to your lumbar discs, so the nerve in the knees leads directly to the lumbars and can cause disc inflammation if the pain was extremely great.
Between L3/ L4 or L5/L6l2-3A lumbar puncture is usually done between L3-L4 (lumbar vertebrae 3 and 4)
L4 and L5 (in the lumbar region)
A bulging disc is a condition that occurs when there is a tear in the outer ring of one of your intervertebral discs, causing the soft portion to bulge out and out of place. If you have a bulging disc, you should definitely get it checked out asap in case it gets worse. If you start feeling pain from bulging discs, I would suggest trying to use some natural methods to relieve the pain - I found some great methods that helped with my back pain - see related links.
Lumbar plexus
grade 1 of l4 and l5
It's the safest area for "lumbar puncture" where needle is inserted either above or below L4 vertebrae.
lumbar: L1,L2,L3,L4,L5 sacrum coccyx
Bulging discs are fairly common in both young adults and older people. They are not cause for panic. In fact, abnormalities that show up on MRIs, such as bulging or protruding discs, are seen at high rates in patients both with and without back pain. Most likely, some discs begin to bulge as a part of both the aging process, and the degeneration process of the intervertebral disc. A bulging disc is not necessarily a sign that anything serious is happening to your spine. A bulging disc becomes important when it bulges enough to cause narrowing of the spinal canal. If there are bone spurs present on the facet joints behind the bulging disc, the combination may cause narrowing of the spinal canal in that area. This is sometimes referred to as segmental spinal stenosis. The human spine is made up of 26 bones; grouped as follows: * 7 Cervical Vertebrae - in the neck * 12 Thoracic Vertebrae - that articulate 12 pairs of ribs * 5 Lumbar Vertebrae - lower back * Sacrum - Fusion 5 of Sacral Vertebrae of lower back * Coccyx - 'tailbone' which is a fusion of 4 Coccygeal Vertebrae In between these vertebrae we have our discs (shock absorbers)

Lumbar Plexus
it basically means that there is a small herniation (or bulging out) of one of the disks in your spine. L4-L5 is the position of the disk in your spine, and refers to Lumbar spine disk 4 and 5, aka it is to do with your lower spine. it can cause pain, or numbness and tingling in you lower legs in SOME cases..
