Knee pain may be caused by lumbar spine problem.

The human body has sciatic nerves and femoral nerves from the lumbar vertebrae, which are distributed all the way to the lower part of the body, while the hip joints have obturator nerves. This nerve line continues to the direction of the lower extremities and also passes through the knee joints. When the waist and hip lesions appear, they will stimulate the nerves in the waist and hips to send a pain signal to the brain, which the brain thought it is a signal from the knee joint. Any unhealthy condition from lumbar vertebrae of the 4th to 5th part will affect the sciatic nerve, results in knee joint pain, sore and heavy limbs and other symptoms.
