All kind of back pain can be cured in 36 hours by dehydrating or limiting water and other liquid intake to the bare minimum. It applies to all types of sciatica pain as well.
A number of people have benefited with this.
The physiology of this is -
Due to excess fluids in the body the tissues carry excessive blood. The tissues are encased by a thin layer called fascia. This causes slow movements of tissues and fluid against the spinal cord. Over a period of time this causes inflammation and pains.
None of the tests or any other thing is needed. Just plain dehydration.
For a faster and complete long term relief there is a small exercise which helps with removal of excessive fluids faster by relaxing the fascia.
