The Throat Chakra is concerned with communication. It allows us to transmit our thoughts, ideas and desires. It is also the means by which we express our creativity. Sore throats and stiff necks can often be indications that there is a problem with some level of communication. Often something is being held back by force of will that would be better verbalised in some way, or a desire to express individuality is also being stifled. Without this natural flow of communicated energy travelling out into the world, other sorts of energies also slow down and there is a danger of stagnation. At the Physical level, thyroid activity may be disrupted, leading to states of either lethargy or hyperactivity. Muscle stiffness in the neck, shoulders and jaw results in a lack of energy flow in those areas. Chronic tension in the jaw can lead to headaches.
