Scientists have created an “oil” for joints hailed as a breakthrough for millions of arthritis sufferers. The wonder treatment is said to work better than anything used currently to ease the crippling disease. The synthetic substance stops the destruction of the joint and also appears to protect against further damage. It is hoped it could bring long-lasting relief for sufferers left in constant daily agony. The chemical mixture was originally produced for another study but scientists in America realised it could be used in the battle against osteoarthritis.
