Sciatica is pain, tingling, numbness, and/or weakness along the course of the sciatic nerve. The sciatic nerve emerges through deep muscles on the back of the hip, and runs down along the back of the thigh. It splits at the back of the knee. One branch continues down the back of the calf, another goes around the outside of the leg to the top of the foot and toes.
Scoliosis Usually Begins in the Cranium
Distortion in the position of the cranial bones causes the spine to become twisted and side‑bent. Then the pelvis becomes side‑tilted and twisted, the positions of the ribs become asymmetrical, etc.
How Does the Cranium Affect the Spine?
The cranium (skull) is lined with tough, dense connective tissue (dura mater). The dura continues down through the spinal column. This internal connective tissue is continuous from head to tail. If the cranial bones are tilted, twisted or displaced to one side, this creates tensions that are transmitted downwards through the spine, all the way to the sacrum and coccyx (tail bones) via the connective tissue.
Cranial distortion also changes the shape and placement of the orbit (eye socket) and the position of the semi‑circular canals (balance mechanisms in the inner ear). You want to place your head so that the world looks and feels level (righting reflex). But If your eyes and ears aren’t in the same places, you may need to have your head tilted or rotated to do this. So your spine has to bend or twist to support your head
TMJ Disorder or Syndrome is a term often used to describe temporomandibular disorders (TMD), which occur as a result of problems with the , jaw joint and surrounding facial muscles that control chewing and moving the jaw. The temporomandibular joint (TMJ) is the hinge joint that connects the lower jaw, or mandible, to the temporal bone of the skull. This bone is located immediately in front of the ear on each side of the head. When healthy, the joints are flexible, allowing the jaw to move smoothly up and down and side to side, also enabling one to talk, chew, and yawn. Muscles attached to and surrounding the jaw joint control the position and movement of the jaw. For the purposes of this article, the term TMD will be used to describe the disorder, and TMJ will be used to describe the actual joint.
People with temporomandibular joint disorder (TMD) experience severe pain and discomfort that can be temporary, or it may last for many years. More women than men experience TMD and this disorder is seen most commonly in people between the ages of 20 and 40.
