Rheumatoid joint pain - arthritis - is a signal of water shortage in the painful joint.
It can affect the young as well as the old. The use of pain-killers does not cure the problem, but exposes the person to further damage from pain medications. Intake of water and small amounts of salt will cure this problem.
Low Back Pain and Ankylosing Arthritis of the Spine are signs of water shortage in the spinal column and discs - the water cushions that support the weight of the body.
These conditions should be treated with increased water intake - not a commercial treatment, but a very effective one.
Not recognizing arthritis and low back pain as signs of dehydration in the joint cavities and treating them with pain-killers, manipulation, acupuncture, and eventually surgery will, in time, produce osteoarthritis when the cartilage cells in the joints have eventually all died. It will produce deformity of the spine. It will produce crippling deformities of the limbs. Pain medications have their own life-threatening complications.
