perthes disease sufferer and real focus on nutrient dense foods with high magnesium and vitamin c made big difference in health and overall pain levels. Also some nautral collagen supplements greatly improved pain and mobility...these simple non drug things allowed me to put off an inevitable hip replacement operation. Now 2 years later with simple health diet changes better life without the pain and 10 fold increase in mobility. Allows me to play squash, tennis and other sports where as before i simply could not!
