Lumbosacral neuritis is a condition in which the nerves located around the lumbar and sacrum become inflamed. This can occur from infection, inflammation, compression due to a small bone spur or tumor, and sometimes diabetes. A herniated disc is a very common reason for diagnosis.
Symptoms include low back pain and shooting pains down the leg. There may be associated weakness of muscles along with some alteration in the sensation of the skin on the leg.
