Relieve arthritis pain with water! Rheumatoid joint pain - arthritis - is a signal of water shortage in the painful joint. 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 potassium will alleviate this problem. Low Back Pain and Ankylosing Arthritis of the Spine can also be signs of water shortage in the spinal column and discs - the water filled cushions that support the weight of the body. These conditions can also be treated with increased water intake.
