New research shows that the pain signal may be simply an "electrical leak" from an ion channel. As previously written there is a connection between the opening and closing of ion channels and electrical polarity charges. The new finding by a team of scientists at KU Leuven indicates the actual pain message is electrical and is short circuited due to chemical changes in the ion channels. The ongoing research is showing the chemical and physical relationship of pain and electrical polarities.

Often the pain can be reduced or eliminated using daily 20 - 40 minute at home interferential therapy but the interferential electrotherapy should be supplemented with exercise and stretching. This video explains massage technique, including trigger point stimulation, that helps increase muscle elasticity, decrease pain, as well as increased blood flow for rapid healing following stretching. The negative charge of interferential therapy may also reduce the swelling due to the inflammatory response of sciatic nerve bruising.
