Chiropractors view migraines as caused by pressure on nerve endings in the head resulting from a chemical imbalance in the brain. Since the brain controls the entire body’s function by communication through the nervous system, any interference to this communication effects the body. If any spinal bones, which protect the nerves, get misaligned, there is a negative effect on the body’s systems. Muscles attached to spinal bones overreact and become spastic and irritated because the nerves stretch and become traumatized. Headache pain can easily result from these imbalances.
