However, that feeling is only caused by the swelling brought about by the hormonal changes in the body during this time of the menstrual cycle. Constant pressure applied to this area will relieve affected females of the menstrual pain that could often lead to being immobile for a day or two. Pain relievers have been formulated to help ease the pain; however, some users of this drug have developed immunity to its numbing effect that they are required to take large doses before finally feeling the ease. Now this has become the basis for the modern reflexology that is known right now, and during that time this was known as the 'Zone Therapy'. The official introduction of the word and the modern concept of reflexology in the western culture happened in the 1930s. And this was made possible by a therapist named Eunice Ingham. Reflexology uses a map of the hands and feet, the map indicates the body parts and the organs to which the hands and feet points represent. In most reflexology practices the feet are primarily used for the pressure points, though the map for the hands are also useful for those who would like to perform reflexology on themselves. There will be times wherein points in ears will be tackled as well. How does the reflexology treatment starts As with any session associated with reflexology, it will always start with the fingers and the toes. And the practitioner works on the heel then the sides and top will be covered as well. The idea in addressing all points is that the intent of the practitioner is to cover all the internal organs. The gall bladder stores bile which the liver produces, it also releases the bile when food containing fat enters the digestive tract. The bile assists in digesting fatty food by emulsifying it. When there is an oversupply of fat in the digestive tract, the liver and gall bladder are overworked yet the bile is unable to help digest the food. If you feel that your headache is caused by vision problem, press the area between your ring finger and index finger. If you are not sure which eye nerve is affected press one area after the other. Most of time, the affected area would hurt a little with a soft press. Do not squash or over press any of your reflexology points because that could lead to injuries and bruises.
